Some pixel and drawing things:

Nice man! I seriously like how that first pixel thing looks, if that was a game I'd play it. The only thing I can really say in terms of cnc for your other work is that your lineart is pretty sloppy, it would add a whole lot more than you think if you would take that extra time to just polish off your stuff. Also, some of your poses seem kinda stiff, but aside from that you're pretty set dude, keep up the good work

Yeah the pixel art is nice man. On your poses and stuff though, they do seem stiff. You should look into getting a bit looser with your strokes, the stiffness and timidness really shows through the linework. Show some confidence with the lines that you put down ya know. Gesture drawing is usually good for that, just keep in mind to get the most use out of one stroke while you're doing it.

i kinda suck at drawing so im just going to say GREAT DRAWINGS!

GREAT! Draw some more!

just some flaws on the inconsistency in the lines. Put in the strokes more confident and daring. You always have the undo button to make it right. So let the strokes be more smooth. I really appreciate the effort you are putting in. Trust me, its going to help you a lot more than you know. So just keep doing what you started. GJ!

They look aight for game sprites. I've never been really fan of pixel art unless it's something like this:
