Good one there!
The render blending is nice, creative, maybe a bit overdone. The render needs some lightning though.
The textures on the render looks okay, but it doesn't look so 'natural'.
The text needs work, it actually looks like its saved in a bad quality jpg. The lines is a little disturbing too.
Background is fine, would be nice with some lightening up some places so it doesnt looks so monotome.
But in all it looks really good, get that right. Maybe your best yet?
Keep it up!
