I like the style you got going in the cartoon sketches. However you seem to be applying that cartoonyness into the life drawings. Try to focus on the natural organic lines in the figure when you do studies; you'll find that things in real life aren't quite that sharp.
I really like the last one - nice crisp lines and cute character designs.
I agree with Toxdel about the life drawing: your stylizing is good, but if you had a really tight grasp on anatomy, it would be even better. So I would suggest trying to stay true to reality when studying it, and once you've mastered that, take it to the next level with your style.
Nice sketches. I like the anatomy studies, but I'd love to see some more finished pieces with color. In the first post, the second drawing seems to have arms that are too skinny for the rest of the body. I'd like to see more stuff from you.
good stuff, love the cartoon stuff (did you get the alcoholic robot idea from futurama?), you might want to try a more skeletal system of sketching, although your outlines look good too.
Oh and you win a fencing match by touching your opponent with the blade (different rules can apply, but usually its just the torso that can be touched with just the point of the foil (blade))
While I may not be much of an artist, I am more than happy to help with MATHEMATICS! I have over 3 years of tutoring experience, and would love to help you out with anything up to and including calculus Also, as a mechanical engineer, if you want feedback on realist sci-fi or other technical critique, let me know, I'm happy to help!
Nice flow with your characters, I especially like the pumpkin head type one as it's got a good feeling to it.
Like to see a lot of this vectored, looks like it was made for it [don't mean to pigeon hole you].
Would love to see more of your characters.
Your figure drawings have really good rhythm to them and I like the expressions you give to your characters. Also you do very interesting things with hands which is one of the most important things to do in my opinion.
I think you should work on shading up some of your line drawings (easier said than done right?)
