>>2677448what program and tools do you use? i think the main thing you should work on is your line quality. a lot of your images seem very pixelated
some of the blurs on your shadows/light look a bit unusual too with some odd blurs, so i think it would be better to focus a bit more on just cell shading. some of the shadows confuse me a little, as well (for the balls theres a highlight ontop of a shadow, and the right ball seems a lil unnaturally lit from underneath, when most of the light source seems to be on the top left
you do seem to have a pretty good grasp of anatomy though, and especially how to exaggerate and play with it. in the first pic you posted as well i really like the expression you do! though some variety on the top/bottom i think would be good, since it seems the tops usually have the same expression as well as the bottoms
