Hello there ! My attempt for the pinguin, I will do the two others soon, but will apreciate some feedback on this one. Also do you think it can be beneficial to post previous exercices on CSI ?

What I noticed the most is that you are not comparing your values. This is a common thing amongst beginners because they haven't trained their eye to see values correctly yet. I gave you some notes and did a quick sketch to show you what I mean, I hope it helps :)

Hey lepetitprince, Congrats on your start on your artistic journey. To begin with, it's obvious your thinking gesture in these drawings because it really shows. Nothing feels stiff and there is a lot of movement in your drawings. Going forward, try to find the long uninterrupted gesture line that describes the pose from top to bottom. Also, try to draw larger and use your whole arm to draw, not just your wrist, this will make your lines more fluid. I did a quick sketch over one of your drawings to show you what I mean, I hope it helps :)
