Astral’s cool, good story too. I would think the hair should be translucent too? Not as much as the skin, since it’s darker.
Girlfriend’s scene: Which media are she used to? Good translation of skill. 
I think the red clouds would look better translucent. Great work on the background otherwise. I would suggest a translucent Insignia Tech circle on her left forearm to make it look more natural. The male’s nocking hand and top could both use some masking practice. There’s a tutorial on here somewhere for making a top in two pieces to go with the 3/4-face torso. Great beginning.
