How did you create the piece? The lighting is generally excellent and the sparkles/smudging makes it feel dynamic. You selected an excellent render too, which brings action to the piece. 
This does break the flow a little. It also feels like the white mouse with red stripes and two blue spots shouldn't be there. But other than that, it is quite excellent. 
It's absolutely gorgeous! The dark and light shades are perfectly balanced by the smudging effects. The render is striking. The text fits into this piece quite well too, balancing against the render, and it appears you used a clipping mask! How did you create this piece? I'd love to see a tutorial!
The brushes don't QUITE flow as well as they should but aren't obvious enough to be too distracting. The blue and red brush to the bottom right side of the render balances against the eyes, but doesn't feel entirely necessary - I like the idea of her eyes standing out as the only piece of bright colour in this piece! 
but lighting could be improved a bit IMO but good job, keep up the work
and it is one of my favorites as well, I'll PM you when it's done
