I am sorry for posting these three ones but I am just really fascinated with those background images right now. Well, I love the fact that I was still new to the software when I made these background images, that explains the poor quality of the resolution. Sorry for that.
See what you can do with photoshop or any other editing software, it's definitely wonderful. I remember being happy like a kid when I made these. It just lightens up my mood, thus considering this as my stress reliever.
