Somehow, yours has more expression than the original.

And here is all the prep-work I have time to do, I wish I could haver refine the design more.

They look good, you are definitively simplifying to the basic forms without getting distracted by the contours too much. I don't know about animal anatomy but I feel like in the 2nd bear and the big cat of your third page are little stretch out in the zone between their pelvis and rib cages, but without the reference photos I can't know for sure, but in any case you did good job, i think the biggest thing here are the perspective of the building blocks themselves and the proportions, but the perspective would improve when you start actually focus on studying perspective specifically and you'll learn about proportions and measurement later on in the course. Keep drawing boxes and cylinders from life and start practicing drawing them from imagination, maybe watch moderndayjames videos on basic perspective to keep in mind while you do this and maybe do a couple more pages of these animal simplifications. Overall you are ready to move on to the next class.

One last page that didn't went through before because of the 10 images per submission limit thingy

Alright Felix, these are not bad, but there are 2 major things to improve here, the 1st is size, these are way to small and that size limit is stopping you from pushing the poses further, 2nd is line quality, now this is something you are going to improve over time but it would not kill you before your start your drawing session to fill a page or 2 of circles and ovals in various sizes and widths. Here's what I want you to do: #1- Draw bigger --you don't need to a bigger sketchbook, thou I would recommend it-- you can just draw bigger but less-per-page poses in the same sketchbook, not only you'll have more space to push the poses but you'll also visualize better the result before putting pen to paper. #2- What I said before about filling pages with circles and ovals, this are warm-ups that would help you loosing up before drawing. And you need to learn to draw using your whole arm specially from the shoulder so you have a bigger range of motion. Stan has a video about drawing from your shoulder, and there are several others on the internet about the topic. And you need to draw from your shoulder to your whole arm if you want to draw bigger drawings because the wrist and fingers have a more limited range and motion. Also train yourself to draw with softer and cleaner lines with just a few strokes, so you have a less messy drawing, then you can add harder lines on the contour of the bean and wrinkles. #3- Get different photo reference, I see many of these are from the examples Stan puts here. And that's good, humans learn by copying what others do, however this is something we should not abuse. Now we have knowledge but we need to know how to apply it on our own in order to keep it. So look for photo references that don't have a bean drawing next to them and draw YOUR onw bean of them, And do 30sec to 1min poses because like the Gesture exercise it would train you to ignore the details and focus completely on the motion of the torso. Here are so good library of poses and you can subscribe for free and they won't ask for your credit card. https://community2.lovelifedrawing.com/c/reference-library/ Good luck.

This is where I stop. What do you think I should work on now?
