Hey, mate. I really liked your sprites. They are free for use? Like, it's ok to use it in a game for free (obviously putting the credits for this amazing art)? Or you have to pay something? I know that if I want some specific, I have to pay a comission, but the already made and posted in Deviantart are free or you have to pay a comission to use it? Sorry if it's not easy to understand, english is not my native language.
