Daiv, I hate to break it to you (and I'll edit this post if it is flaming), but your spritework sucks. Period. It sucks possibly worse than Dlbrook's tiles, and he can't even recolor tiles properly. The only people who actually like your work are completely blind. Perhaps if you actually attempted to get better, your work wouldn't make our eyes bleed. The only time when you shouldn't use a black outline is when you are good enough with color to give the illusion of a seperation from the rest of the environment, which you are not. If you aren't ready to ditch the black outline, then it's perfectly okay to have one. That's it.
So is putting someone down your way of trying to motivate them to do better? Shame on you, Revman.
