I absolutely love criticism and critiques.
Some of my avatars, signatures, and wallpapers will contain fan art. I do not claim to own said fan art I only put it together in the creation. If I know who created the fan art I will credit them but if the source doesn't seem reliable (google images, 4chan) the fan art will not be credited. I just wanted to make it clear that the fan art that I use is not mine and I do not own it.
The two below were originally made as wallpapers for my old phone but they could be used as signatures as well.
Wallpapers - I don't make a whole lot of wallpapers for regular computers anymore. I started dual-screening last year so I've been making wallpapers for that.
I don't mind at all if my stuff is used. All that I ask is that you give credit where it's needed.
