That's a pretty nice for a 'random doodle' :)

If I might offer some constructive criticism, though, the (charater's) upper left leg seems thinner than the right leg, despite being closer to the viewer and therefore by perspective should be larger. Also, the knee has that sort of... jutting out part, which is far too exaggerated and makes the leg look disjointed. If you want, I could link a few vectors to demonstrate what I mean.

<3 thank you very much ! i didn't even notice how bad that leg looks when i did it last night

and yes please! any help is appreciated
