Not fond of the shading, its pillowed and done sloppy. And it looks like Link isn't standing on the grass because there's no shadow. And the word moon looks very plain and boring to read, and I don't think the word should be on it twice. You should also color the outer part of the card and also transparent the outer white (theres sites that can do that for you idk their names), most of this looks really rushed and done lazily. It has potential, but come on, add some detail!
ahh, thanks for the advice, Anubis, i did rush it XD and i was limited with colours, otherwise i wouldve made it more detailed n stuff, but yeah, ill keep in mind what you sayd =3
