At first I was thinking of putting doors and window plus a bed and all the usual bedroom stuff but then I feel like it's a bit generic. And then I thought about maybe doing abstract or surrealistic; something like Yusuke Nakamura. I'm really stuck and can't decide on this one.
Also, I'm not so sure about my color choice. The blue wall is horrifying. I'll change Mio's hair black, the dark blue will be the highlight. I like the green of her headphones but I'll probably make it darker and less bright. Black shirt and pink skirt is what I'm not satisfied with most. I can't seem to find the right combination for the shirt and skirt :( How about blue skirt and white shirt? If you have any other color suggestion for other things such as her hair scrunchie and whatnot feel free to comment :)
