Yo duuude, so Im a beginner, so take this with a bag or morton salt:
Row 1 left, SWEET druidess, the monacle is on point. Something about the bang on the right side of her face seems choppy.
Row 1 mid, that bandana is super contrasted with the face below it, and thats probably from the border colours. The body on this one ROCKS.
Row 1 right the collar and chest orientation are mismatched, but the face is SUPER clean.
Row 2, the right side of her face and hair are super split up, the border colour separates them pretty handilly. Maybe try blending those? Her face on the right side, the eye is pretty high up, maybe down a pixel?
Row 3, her hair on the right side going over the pauldron, probably some sort of shading needed. It'd make a shadow in real life, I feel like?
Row 4 left, LOVING the darker dude's colour choices. give yourself more credit, the body looks aight! The right hand side where the cloak comes under the pauldron is a bit wonky, but those details are super hard to nail down.
Row 4 mid, this is probably the most obvious splice, but only because you diddn't do too much to BabyZeph's head as a base. The royal blue of that cloak also hurts my eyes a bit, it's almost neon. The left hand side where the cloak goes over his shoulder also needs a bit of blending to smoothe it out.
Row 4 right, thats above my pay grade.. but if I had to guess, her right shoulder needs some TLC. I'd just match it up with Lalum's dancer ribbons, like you did on the left hand side, at least for now. that should give you some leway to focus on the the only real issue, the headpiece. Thats a ballsy sprite, dude . The head piece could probably be lightened up a tad. ignoring the wings, i'd say try blending the part where the headpiece goes across the forehead. With my jewelry pieces on my folks, I usually use the same as the darkest shaded pixel on the skin to help it out.
Heres to your good luck! Hopefully thats not overstepping nuthin'!
