And you're incredibly skilled at being stuck on yourself, but you don't hear me complaining.
If you want critique on your 20 second recolor, here it is (though you'll probably just cry and whine and moan like you did the last time):
1.) The trunks of beach trees are never that color. Ever. The trees grow in an area where there is usually a lot of sunlight, and also where there's barely enough nutrients in the ground to even get as tall or as thick as the large ones are (though admittedly that's the fault of the original tileset, not you) unless they're directly ON the water. The original tileset had the coloring at least relatively right. If you do want to change them, I suggest exercising your Google-fu to look for pictures of trees found on or around beaches and rocky areas.
2.) The cliffs don't look right, you totally botched the recolor on them. They look like they want to be brown, but are still struggling to be grayish. Again, simple Google-fu research and time can solve that problem.
3.) Your shadows are fucked up; it looks like you tried to do them yourself in Photoshop and didn't make the shadowing layer transparent enough. You need to fix that.
4.) Your grass -- and anything green for that matter -- are way too bright. It clashes horribly with the brown-but-I-want-to-be-gray rocks, and just generally sticks out like a sore thumb.
