While I like some of the stylization in your characters, I feel like your anatomy can use work and you tend to hide it with the style. If you're serious about becoming a character artist, you should do some serious anatomy studies. This will definitely strengthen your stylized characters as well.
i'm digging the style. textures seem a bit inconsistent though. some feel pretty stylized, others are clearly photosourced (cgtextures? they look familiar). even if you're going for a mix of modern and old textures, they should use a similiar stylization. some normal maps look weird, for example diamond plate texture.
Hi! Just a suggestion but if you want them to be more readable from farther away you can exaggerate your shapes a lot more. Especially since this game looks like its pretty stylized so far itd be cool to do some fun wonky things, like this for example
stylizing =/= missing human anatomy if you are doing a human character, stylized or not, the eyes need to go in the center of the head or everything looks wrong. You also need the basic form of the skeleton underneath or the face will begin to not look right. Saying its stylized isn't really a reason not to have those…
