Yeah, I thought this was a rock. A good rock, mind you, but a rock nonetheless. But I suppose context will help sort that out.
It has a great sense of depth and I like that it's not monotonous. Even though I know it's a cloud, I could actually see this being a rock just as easily. Maybe a little more pronounced fluffiness would make it more cloudlike?
Think ya mean banding and yeah it's a nice cloud with already a sense of atmosphere about it which is pretty impressive for a single cloud sprite all on it's own. Hope the rest of the graphics are up to the same quality.
Clouds... rocks...
Clouds... bushes... what's the difference ;)
