"I really dislike the lack of cross-section tiles transitioning":
Wait, wait wha?
I'm not sure what you mean by that. Could you be a little more clear?
"Yer trees don't really qualify as trees, they're just wiggly brown oddly hollow pillow-shaded pipes jutting straight up with boughs at random that have an opposite light source for some crazy reason (sun is top right, yet lighting is coming from bottom left? are we in china?)":
Why does it always take someone else to spot pillow shading?
Yes, yes we are in china, cough.
"why not have a trunk tile as a base, maybe some vegetation, an attempt at textured treebark, rather than smooth - refer here. Heard of tile variations before? - I know you've seen them--multiple versions of the same tile that can break up repetitiousness."
Yes I have. However, are you sure that's the correct thread your trying to point to? I'll see what I can do about the shading though. And to think it's spotted just After I finish the newest piece. I'll see what I can do about the clouds. Even though I thought it was earlier agreed that they were generally okay. Got a whisker?
Thanks again.
You're welcome. I learn from this as well you know.

Here I've addressed a number of things. It's funny that Ai just posted - the palette I decided to pull colors from was shown to me by him (her?). Anyway, it rocks so far. My modified version is wroght with crappy mistakes and problems, it's just for show, it was done too hastily.
-Decent depth achieved in sky with only THREE colors. Gradient is messy, though.
-Clouds given volume and character, imagine them floating by slowly at different speeds, all on their own bg layers. Notice the farthest cloud not using the highlight shade - this and it's scale make it appear further away than others.
-Walkable ground defined with small edit to grass tiles
-Made 3 sets of transitioning cross-section tiles (my own ignorant nomenclature, btw). Despite the obvious tiling problems do you get it now? Your version presents the eye with a depthless plain of monotony, pulling the eye down to bottom of the image, gotta keep the eye where the action is. You could
greatly benefit from studying basic design principles,
do not underestimate their importance.
-Trees turned into cut off bean stalk things with only a color edit, they seem a little more excusable now.
