Good one mate!
Some really good ideas here i think.
The render is good, really nice and simple textures, with good blending on shirt and nice desaturation
The background is okay, but needing some background textures, at least in the left part.
Patterns is working really well though.
Lightning is okay, i like the right part the most, really good!
Text is okay, but too tiny with that style i think.
Keep it up mate!
PS. Come on guys, some comments!
