I didn't know one could be vored twice at once!
Anyways, I think your shading needs a bit more contrast and might need more careful consideration. Right now, just about every part of the ponies' bodies is at least moderately lit, with the exception of the left-pony's hair. This implies there's several lights all around, or very bright lights obstructed by lampshades, but most of the highlights around Nova imply that the light source is the soul. It's hard to know which and how many lights are in the scene. Also, being directly lit by lights, as opposed to light bouncing off of walls or being obstructed by lampshades, it usually sharpens the points between light and dark. If the soul is the only light source, and even if it's not, the light it produces should look a lot more like cel-shading, with a rather sharp falloff between what it illuminates and it's shadows; In other words, soul-light probably shouldn't be depicted in gradients.
With all that said, props to you for so consistently shading all of your artwork! Excellence is a habit, and there's something excellent about consistently shading everything.
