Why? Idunno, cuz.... I actually don't like it
I'd say... enlarge Miku, raise her and put her in the right third of the canvas. Drag and maybe rotate the paintwork so she is surrounded by it, but it is behind her on a layer.
Look up Rule Of Thirds on Google and you may find a sweet template of composition rules that you can put on your work, then hide for the final image.
I love wallpapers so I'm always out to help people. I'll follow you, keep up the cool work!
Thanks for the advice, in all honesty, I've been having trouble with ideas for these wallpapers, but not with the want to make them. This wallpaper literally only took me 5 minutes, and I thought about making it go all around her, but with everything I did I hated it more and more and decided not to fuck with it anymore
