CreatureBox Style Self Background

Based it off of the fine website design of creaturebox.com, gonna edit it and use it for my work Tumblr (whenever I get around to actually using it)
Took an entire night from about 6pm to 2am since I designed everything from scratch
And yet still the horizontal paint lines look awful and just WILL NOT SHARPEN no matter what I do to them augh
I'll figure these things out eventually
