Those kids you always see

Anderson.T : This was originally meant to be a sample or a sort of test for my Triton comic. Didn't began at all, as you can already see. But then there was this other comic I was trying to make which was meant to be a spinoff-ish story in a same world, and introducing a whole new set of characters, including that girl at the bottom left.
Obviously I had little experience with black and white and shades, especially concerning digital work. So now everything looks too dark and the shades are clumped up into this one big thing because there's nothing to separate them (I'm reffering to the clothes for instance). so I should get a thicker outline, and use much less shadows and use black and white instead.
maybe the shadows are overly detailed or simply needs work. idk
