tileset help.

I'll just say it's pointless to try to recolor pics1 to your liking. There are a few reasons as to why:
1) It rarely looks better.
2) Because of what you did... just messed with contrast/brightness.
3) People are familiar with pics1. Changing it invokes familiarity but with a huge topping of "eww, I hate change." Especially when combined with above reasons.
4) What's the point?

Also, ditch the emphasized shadows. Rarely does a game pull it off artfully, and I can't say I've ever seen a 2d game do it. In fact, only a few games come to mind. One is Okami, and the other are a few comic-book-based artstyle games... which I can't even recall by name. Again, like I said... can't say I've ever seen it in any 2d games... Though I guess NES games did it, but that had more to do with limitations than anything. Never on a top-down game, only platformers. Just don't waste the effort.
