not liking the lighting on the 2 sides of her or the entire blue.. various colors would look better..
lighting on the left part of her head is wrong..... its exactly where it shouldn't be >_< colors need some work too.....
thx fx near her face on the left is a little to sharp too poping out.. really disrupts the tag.. else all well done imo.. depth and flow wise..and the tone is good..
Only thing i can see is it looks like nothing's blended, really. Blending would make the lighting look fine, i'm sure.
