for study: an unicorn on its ambient of studies,in a way you can focus on their environment and lighting from magic as main light source for fanservice: fluttershy blushing in one of those "virgin killer" sweaters
my own taste: Something envolving combat armours,vintage instruments,"pony religion" and Steampunk
I just want to see more of those hips and thigh gaps of yours, hue. That or, maybe something dark contrasting the cute like ponies at an edm club taking pills. I always enjoy your way of making lights and the shading that comes with.
An idea for shirt designs: a pony looking out of your (also drawn) shirt pocket. Maybe each one in a different way?
Oh, and to add to Queen Chrysalis requests, I have an idea for a piece. Considering that now she got no respect, no crew, no base and only her own skills - I can't help but think of an illegal graf artist Chryssi, who is trying to get up to former glory. Think of it, with their shapeshifting abilities, changelings would have it easy with avoiding legal "problems" like being arrested for trespassing and\or vandalism.
(I miight like Getting Up: Contents Under Pressure a bit too much.)
