Two issues with this image just stand out to me.
1) you're zoomed out so far the cave looks like a teacup, or a keyhole
*EDIT* the black thing in the cave is the ninja, the cave roof from the outside cuts his head off*/EDIT*
2) the 3d particle based clouds I slaved over look like shit
Well... one is easily fixed by zooming in, but what about two, surely I can take a half-hour out of my schedule to make my work look nice, surely...
I think it looks much better now =)
