The colour scheme is actually really nice.
Personally not a fan of gfx work with Kpopstars, the picture you used doesn't really fit with the background style but I guess if you like to see Kpopstars this works out.
I wonder if you could spend a bit more time on a new piece in this style with slightly different colours and a different image and see how that works out if you compare it afterwards.
Kudos.
