Hi othmane, using one box to establish perspective is a good idea but I suggest you use two different ones for shoulders and pelvis; this will make it much easier for you to move your figure. Imagine you have one of those articulated puppets. In the horse's snout you don't really need to use a circle for the nose, keep it simple with a wedge. The head of the rhino on the other hand is narrower as you get towards the mouth, let's say a wedge will do here too. The legs, in both cases, should be more sinuous. In the horse I can see that you started with a simple curved line, which is correct. When you draw the structure you have to look for ways to maintain this curve: it may be suggested by a bone sticking out under the skin or by the curve of a muscle. If you'd like to try a different exercise (I know that's not what this exercise specifically requires, but I'm a bit of an animal nerd and I like to teach people how to draw them. And then you'll apply the same reasoning to the human figure, when the time comes) Take some photos and try, maybe with a sheet of paper, if you can't do it on a deno program, to draw these lines on them, to see which landmarks outline them.

Hi, your lines are little messy i would suggest working on your line quality , if you're trying to rush because the time is just not enough i suggest adding more time as long as you keep focusing the motion not the coutures.

i'm fairly new to color theory and honestly i think each person of every skillset can take something out of this course.
