I would appreciate it if you credit your resources (mainly it is the render/scan/picture).
It is always good to re-use colours from a render in your background. The little bit of purple in the clouds looks kinda off though. Did you render the picture yourself? In that case, you are doing a pretty good job! If not...well...start rendering them yourself.
I'm not sure if I like two different styles mixing in together. Grungy paint, grungy illuminative clouds along with very neat patterns (the blocks for ex.). You get the best results by picking a theme and have similair styles which really works together. The only things that makes it all blend in is really just the colours.
Be sure to add the sources, especially scans in every next submission.
