I do photoshops for the most part. Most of what you'll see on here are special effects, sometimes you'll see stock photos that have been manipulated to look like a superpower being used, or a mythological creature.
Take a look through my gallery! I'm confident I can do whatever superpower effect you'd like. As for the cost, we can talk about that after you come to me about it. :D That way we can both be satisfied that you get what you expect, at a reasonable price!
