Your paintings have improved a lot. You are varying harder edges and softer shading well so it doesn't look like a blurred image. In my opinion the dragon feels out of place in the composition. It is interesting but feels like it isn't interacting within the environment. The contrast in detail between the two adds to that. Think about the story you want to tell with the two main subjects. "Is the dragon an enemy?", "Is it a companion?" For example, If it were an enemy I would make the two fight, the ship shooting off cannons or the dragon breathing out fire. Right now the dragon is just "there". If I were to take the dragon out of the image the main feeling or story would stay the same. They both fight for attention so I believe it is best to think about which to focus on. Say for example you want the ship to stand out more, then I would fade out the dragon with more of the clouds and atmosphere. The colors look good in my opinion. You could also try experimenting with a nighttime setting to add more drama. Good job and good luck.

Nice job they look amazing! You have a great understanding of forms, lighting, and color.

Your structure is there and looks clean! When you are using shadows think about the structure you are shading and vary it accordingly. If we were to think about the cylinder and how it turns in space and wraps light around it, your gradations should be soft. Especially for your core shadows.

You can also post your work here to get critiques from the community, which I recommend for you to see mistakes you may not be seeing. I'll give you some feedback if I see it! So post your work!

You have shown a lot of improvement, good job! I believe you are ready to add more gestural lines and details to the figure. One thing I noticed, your using 'C' curves in places where there is tension. When there is tension, weight, or sharp joint changes make sure to use a 'V' or zigzag instead. When you start adding more gestural lines (e.g 2 lines for the arm) remember to not follow contours but the motion the arm is going. Same thing for the rib cage and thighs. Using parallel lines for these situations, generally, is a good idea so you dont break the gesture with two sides fighting for the movement.

Gestures are looking clean and expressive! Make sure to pay more attention to your proportions as you make gestural lines. Its not the main focus but should not be hurting your overall design.

The shading is looking great. I would incorporate more separation in the reflected light with shape design and smoothen out the gradations of core shadow to halftones a tiny bit.

Looking good! Keep it up!

The reason you draw scratchy lines is that you are unsure of yourself with where each line should go. So you go through this phase in thinking of, "Is it here? Here? Or Here?" Take the time to analyze the figure. Ghost, and draw long, smooth, fluid lines. Using your elbow/arm will help you here with a greater range of motion. Get out of the habit of drawing scratchy quickly. As time goes on you will have greater hand-eye coordination, confidence, and understanding of line weight. As you continue to practice your gestures refer back to Stan's first two videos multiple times. Try them out yourself, look at how he draws, draw with him, and finally draw it yourself and compare. It is very important to keep your lines clean for readability. Your small repetitive chicken scratches create a chaotic and confusing image. Your cross contours serve no purpose but add to the chaos. Your last image is the best out of all of them. Keep on practicing. Good luck to you.
