Oh, I thought you used a smoky kind of texture layed over your work (the kind you put on in photoshop, etc, like special brushes/textures)! Sorry if I was wrong! I see a lot of people use textures to get awesome effects and stuff--I didn't mean it as any slight to you. I've just never seen the effects like that made any other way. XD
Okay, awesome. : ) Thank you!
As for a theme... hmm. I'll put a few ideas out there and you can see if any spark your inspiration? Like, um... spring is coming up, so maybe something spring-themed. And Valentine's is coming up, too, so something with a V-day theme would also be really fun! Or a beach theme, maybe? And this could be complicated, so I don't mind if you rule it out, but something RPG-themed (with classes and stuff) could also be super-cool. ...That's all I can think of directly off the top of my head at this time of the morning. If none of those spark and you need more ideas, let me know!
