Feedback on my game art?

I made all the art myself in Flash, which I am by NO means amazing in. If I actually get this to the point where I'd sell it, it would probably only be a dollar, so this isn't meant to be super high quality stuff or anything. It's a stealth platformer where you play as a ninja and, well, be a ninja. <img src="smileys/smiley1.gif" border="0" align="middle">

That's an actual screenshot by the way -- the game itself is progressing pretty well. I should have a rough demo in about a week or so.

love the samurai character :) maybe give the ninja also a sword? or show some hands, critique it does feel somewhat overly greenish, maybe more trees?

I was thinking about the sword, but it's supposed to be a stealth game, so I don't want to give the player an easy way to cut down every enemy and not even worry about stealth, y'know? That being said, there's going to be several tools for the player to use instead, like ninja stars, tranquilizer darts, even some magic. One spell I have in mind would let you become an enemy, so if you become a samurai... well, there's your sword. <img src="smileys/smiley2.gif" border="0" align="middle" />

And hands do magically appear when you need them -- hanging off of ledges, throwing ninja stars -- but I've become attached to the basic ninja being a blob. <img src="smileys/smiley17.gif" border="0" align="middle" />

I do agree about it being overly green, I had that concern too. More trees would help, but I feel I need to do more than that... I'll definitely be adding some more small touches like flowers, maybe fruit on the trees, maybe little birds flying through occasionally... Again, those will help, but I dunno if it'll be enough. If anyone has any ideas about that, please let me know!

maybe look at some platformers on youtube or something to get inspired, you could make the ground more brown with grass ontop for example
