These are all pretty solid! I appreciate the effort you put into posing your characters.
The background colors are really nice, I especially appreciate the backgrounds you made for Kanna, Midori, Dewasenja and Inazuma. I default to blue skies a bit too often, I should try different colors sometimes as well.
Kanna’s sitting pose is great! That skirt must have been tricky.
In “Revenge”, the framing is done really well! I like how you posed the characters relative to each other. The guy is holding the sword in a rather weird way, usually you’d want to hold the sword closer to the handguard.
I like the pose and clothing you made for Inazuma. The wind blowing the front part of the skirt and the vest is cool. The arrows in the tree are also a great touch. I think the weakest part of the image right now is Inazuma’s lack of chin. Right now, thanks to how the face is placed looking to the side, it looks like he has a really weak chin and a flabby neck. Maybe play around with the different head shapes and rotate them around a bit? I’ve had this problem as well, it’s not easy to solve. Anyway, I like the picture overall!
