Assignment

When drawing the Forearm, start with the chicken drumstick. You want to start simple and establish all the big proportions and simple forms first. Find the block of the wrist and use it to establish the perspective of the arm. You should know in your head whether the arm is supinated or pronated, and where the ulna and radius are. Then you can draw the individual muscle groups. Get the rhythm of the ridge muscles as they wrap around the arm, from lateral epicondyle to thumb. Split up your chicken drumstick into the individual muscles if they’re visible, and add the tendons at the palm side of the wrist. As you add the individual muscles, try not to lose the large mass of the 3 muscle groups. There’s a hierarchy. Primary forms first, then secondary forms.

Here are my assignments, with these, I tried to understand how muscles twist. I appreciate the criticism.

You @Camellito are doing great with these studies 💪

Could you please upload a model where I can see the entire arm muscle? I don't really understand the muscle connection between the upper and lower arms.

Its difficult remembering which muscles belong on the lateral and medial sides, and had a bit of trouble placing the ridge muscles in poses with an extended arm. Also decided not to focus on the individual muscles within the 3 groups just yet. Learned a lot from this lesson :) any feedback is welcome!

Hello! That is my forearm studies sheet. Thank you for the great reference material!

Forearm sketches. The muscles is complicated, It will take times before it finally click. Any feedback/critiques are welcome

2023/11/29. Good afternoon everybody. Here's a quick review about the forearm muscles. The first part is about the extensor group. Thanks.

This assignment required quite a bit of self-critique to get right! I'm sure I've missed things so feedback and critiques welcome and appreciated!

not much to say, youre really good. Just keep doing what youre doing. You have a good handle on this.

Hi @Madelyn Kuipers, nice studies! - The muscles generally go to the right place, so good job with that👍, but I would try to be more specific about the insertion. I don't necessarily mean putting in every little tendon, you may simplify, but in that simplification it's important that things make sense, so that the arm you've drawn would have been able to move, if it was a real arm. In drawing six for example, you stop the extensor group where the forearm ends. Had this been a real arm, it wouldn't have been able to extend the hand. The extensor group has to attach to the hand in order to extend it. Make sure that each muscle group has a specific point/line where they attach. - If you want to simplify the ridge muscles into a single volume, try to keep it consistent between poses. Comparing #2 and #6, which both are based on muscular models, the simplification isn't consistent from drawing to drawing. In #6 the drawing have indicated a strange split in the middle of the ridge group, which doesn't seem to match the more accurate "Jabba the Hut" shape of #2. I hope this helps :)

Finally getting back into regular anatomy practice!!! Wahoo!!!
Jesper Axelsson
Yippiee!!! XD Cool drawings! They show that you're going in depth with the muscles. - There are some innacuracies here and there. In the top middle drawing for example, it feels like the brachioradialis could reach higher with its origin, and the extensor carpi ulnaris seem to be origination from the olecranon instead of the lateral epicondyle as it should. I think the next step for you would be to focus on nailing the muscle groups and their attachment points. So find the big groups and the point/line of origin and the point/line of insertion. Ridge group. Flexors. Extensors. Thumb muscles. Also you might want to follow a process of: first drawing the flow then fleshing out with the major volumes (maybe a step here where you find the bones) then draw the major muscle groups on top of/into the major forms. Kinda like they were big chunks of clay on a sculpture (you probably want this established before adding individual muscles). This will help making the arm's orientation in space read even better. In the bottom middle drawing, I'm not quite sure how the nearest forarm is oriented. Hope this helps :) Keep up the good work 💪😎👍

Here are my assignements for this lesson ! I just realised I forgot to watch the Anatomy of Flexors/Extensors and Ridge Muscle I mainly used the PDF/3d Model to better understand the forms I also did some bonus ones with a LITTLE BIT of stylisation I'm sorry for the overall quality, my phone and my scanner aren't so great
