Try and get some darker greens somewhere in your palette (use csets 10/11 if they're not in use). ZC does transparencies by averaging(?) the layers and picking the closest colour from the 256 colour palette. By filling your palette with "correct" colours you can get better shadows, and also have a degree of control over them. You can even go in reverse if you want - decide on what colours you want in your shadowed areas then create "shadow overlay" colours that, when mixed with the ground, create the exact colours you want.
Also, he didn't say the grass was dull because it lacked shadows, he said it was dull because it's a very washed out, desaturated colour instead of a vibrant green. Of course there's nothing wrong with having a washed out palette if it fits the scene (e.g. an abandoned or haunted town, or anything depressing) but he felt the name "Decora" evoked a different mood to what's presented.
I'll have to experiment with that, since I didn't know that's how ZC functions. Hmmmmm. As for the shot as a whole, I might change the palette to make it more fitting to "Decora" since it does mean decoration. Thanks for your tips! 
I agree about the shadows, but the screen as a whole is really promising. The color scheme reminds me of the SNES Star Ocean, for some reason.
You're missing a treetop on the bottom, but who really cares?
Thanks, and I didn't notice the tree missing till you told me! 
those are shadows, eh? the ridges don't seem to be tall enough to cast such dark shadows. I'd just take them out. anyway, my point was there is a sharp edge to them and it looks bad, making the tiles obvious where most of them are not.
I see your point now. I'll try to fix it 
Hmmm...You're really close, close enough to give me an idea! One sec...
*Abuses the circle tool*

What if you used big blobby shadows like THIS, and used them on the cliffs like I showed? Would that look nice? I think it'd look more organic than 45-degree angles.
Oh wow, sexy shadows!
I'll check these out when I get a chance to use ZQuest. You have been saving my back lately man! 
Looks great! I'm not fond of how two different styled bushes are present on the same screen but all in all it looks great.
Thanks! I'll see what I can do about them bushes
