I think those are great it's a nice start, you should probably draw your lines a little more curvy it feels a little too straight. And I would recommand drawing only one line for one flow so it's a little less confusing. But other then that great job I think you get it !
I've been working on improving my animal drawings for some time now, and I feel kinda stuck without any feedback. Would you critic those 5 minutes drawing and tell me what I should improve ? I'm mainly trying to get the gesture / anatomy right
