Hey @petrovod !
Nice to see you're back ^^
2 with 3 clothes design maybe ? (shoulder pad 2/3/4 are nice, and 4 arm pad with horns)
Weapon of 3 & 4 look interesting !
Good luck !
The first one looks more urban, although it could still use some tweaking, maybe a cyan, magenta and black scheme? or replace the greens on the first one for blacks and blues, if that is what you are looking for anyway.
Overall, I feel it could use more blues instead of greens, like, referring to the very first face you had, the red/black one with blue strokes behind, seemed very fitting. Just my opinion though
