You want me to comment on something that is almost perfect? :D
You really want me to be hard on you! Maso!

Anyway... I like the matching of all the shading and the color sheme is well respected. You did a really nice work on the color matching of the background and the scan.

The shading on the left bottom corner is maybe a little too dark. So we lose a lot of details from the background which is pretty sad cause of the nice one you worked on :)
Speaking about shading... What's that shadow in the top right corner? If it's a shadow of something like tree or a bush or what so ever... Try to make is less geomectrical. If it's the shadow of a wall or something more geometrical, please make some cleaner edges to it.

Someone else said that the girl's eyes are missing some cold blue... And I would say this person was totally right. In fact you see the blue in the background? Why not use some of it to add a light blue in her eyes. So her eyes would remind the color of the background : green and blue. It would also add some interesting effect of mixed blue-green sort of vortex like coloring... Could be interesting to emphasis the Clairevoyance style... See what I mean? Not usual eyes for an non usual power :)

Anyway... I hope you like this comment! :p Picky as can be! :D
