I like the contrast between the orange/red background and the purple kimono; it was also a very neat idea to place her in kimono and make the whole wall more traditional. :)
One tip though - when vectoring, it's better to use 'shape layers' than paths, particularly when it comes to hair - paths have those ugly blunt tips while with shape layers you can make them nice and crisp. It takes more time to make something with them but the result is worth it. Nice wall and keep it up! :3
