I again must ask for assistance

and that's why you received critique: we know you aren't great, and that we aren't either. We're at constant learning here so don't sweat it if your work isn't up to your standards.

As for your sprite, it's passable for dev graphics, but I want to teach you some art techniques in case you're interested. Notice that the edits that I'll be making upon your sprites are merely for didatic purposes, you may or may not use it as base for further edits.

I'll work on the first sprite; the rest human bases are up to you.

Three steps:
1- Anatomy. Chibi is stylized, okay, but that doesn't make people's heads perfect spheres. There's still some base to follow, and since it's supposed to look cute, some os its esthetics are made to look neotenized (that means, look kinda like a kid).
2- Perspective. It's easy to get confused and end up making a standing guy looking at the screen, but here you are supposed to see everything a littlefrom above. This includes the pectoral lines and all the details you've added. Additionally, from this view you probably wouldn't see the details of his collarbone as they'd be below his chin.
3- Colors. They seem really washed out and it makes it kinda boring; try playing with the pigments more, and don't forget contrast.



I didn't change the colors here, but I tried addressing some of the points stated above. Have fun spriting!
