Blacked out ask.fm (help needed)

I've taken inspiration from team blackout, and I decided to theme my first app. However, I've run into some issues.

Here are my updates

And here are some screenshots


Any guidance on how to improve (especially the pesky create account background) would be greatly appreciated. Note that some colours are set to very vivid ones as I cannot find theme. If you see purple red etc, let me know! I hope to bring more themed apps to you guys!
