I’m not use to doing this kind of thing, but I know getting advice/critique is important to my growth, so here we go…
This is my first time attempting creating a human/cartoonish style model (or much of anything really), and wanted to see what other people feel about my progress before I start refining it.
looks as a nice low poly
if you want more cartoon style, perhaps make legs a bit shorter (like flint stones or other cartoons), and the head a bit taler.
you might set a picture in the background so you can check it with cartoon proportions (they are not like real people dimensions).
Looks like a good start! Before you go further, you should decide on that kind of cartoon style your going for. If you can draw, draw a concept sketch, if not, use Google images to find something you want it to resemble.
