I agree with what others are saying here about the piece. I think that in this particular composition, the unicorn is distracting. The character is beautifully done as usual, the hand is great and wings nicely rendered. I would suggest maybe cropping the unicorn out completely or perhaps expand the picture horizontally and make the unicorn more prominent so that she is resting on it? It may also help if the unicorn is looking in same direction as the character or at her as this also looks like it can be a reflection. (I don't know if that was your intention?)
sorry for super delayed reply,
but thank you so much for the critique!
originally I had more to right and bottom,
but the space had no meaning so I cut off.
then I took your advice and got even closer up to the characters
and now it looks better!
I better think more about the composition before I start drawing
