I love these recent poses, great job! They look very fun and exciting!
For your artwork progress at the bottom, all of the colors you've chosen ( except the sky ) is very dark in value. In a scene that looks to be outdoors in a sunny day it looks it bit too dull. I went ahead and used an add(glow) layer and brightened the whole scene with an orangey-yellow color.
The example is a bit intense, but already I can feel that it's a lot more lively and pleasing to look at.
Another thing you might wanna take advantage of is the surrounding color. Since you added a blue sky there it could add a really nice flavor to add some blueish hints on some of the shadows and some spots that the light hits the mannequin.
Also the ink spell that the mannequin is casting looks a bit messy. There doesn't seem to have been much thought put into it, but is just there to add a bit of coolness to the character, which I totally understand. I love these types of magical energies in fantasy artworks! Maybe try to study how other artists have drawn magic and flowing liquid?
I always say this after I give criticism, but please take everything I've said with a grain of salt, especially this one! I'm very weak with design, color, and lighting so I can be wrong with a lot of things I've said.
