Wow. Stealing art from a forum and then posting it directly in the same forum where you stole it from. Like if we wouldn't notice.

Taken from http://www.wayofthepixel.net/pixelation/index.php?topic=11074.0
And the background is taken from ActRaiser.

Yeah, he's working on Driftwood along with me. Nearly all of the graphics in that screenshot are temporary or stand-in. Including the background ripped from one of my favorite games ever, Actraiser. :)
Well, it clearly doesn't co-operate with the tileset very well at this point, as you have a bit of an angle to the view, while the tileset seems to be strictly a side view.
Also, the greens and reds seriously pop out in comparison to the more subdued hues of the rest of the palette, so tone those down. I also read t he gray color (esp. on top of those tiles) as stone, which may not be what you intended.
The tileset and the color palette are both undecided. I've been trying to find a way to get an overall color palette that doesn't clash, but I have a terrible eye for color. I may have someone on our team do it. If you have any suggestions, please feel free to offer them :) I think he just dropped the enemy sprite into the screenshot. When we put him in the game, he'll be pixelated into an area that doesn't look so awkward.
