Thank you!! *^* When you save in png it should appear a window to save it with transparent BG. But if the window doesn't pop up, then you could save the pic as psd, open it with photoshop, and then save it as png.
Umm, excuse me, I was wondering if I could use this art on the website, Pokefarm.org [link], on a forum template and signature. You see I make backgrounds and signatures so people can use on the site's forums. (Free to use for the whole site as well) And they're requesting Princess Luna~ I came across your artwork and was amazed by it. Credit will be given and I'll even show you the finishing results~
