Looking pretty good, Ocean. I'm detecting a strong hint of Doppleganger's style there. He's a damn good pixel artists, so I can't think of anyone better to learn off. I'd say that your grass work and other ground tiles is far superior to your plants and general objects though. I have a sneaking feeling that if you put those plants over the grass, they'll barely stand out. What I recommend instead of that for plant leaves and stuff, you use dark greens, so they are clear, crisp and identifiable when placed over your various grass tiles.
