Tehre we are, don't worry about getting every little line in there, it's just to show I want a certain amount of detail, like the bush and the leaves in the corner.
Don't laze on the trees just because they're in the background, I need practice colouring them ^_^ If you fine anything hideously wrong with anything feel free to change it, I'm no expert on horse/unicorn anatomy, and I don't pretend to be the all knownig being when it comes to forests.
It's magic collabing with me, in'it? ^^;
Happy lining, on the first layer you'll find some colour options for the unicorn, I'd like it if you picked one because I'm not god at explaining colour schemes in Memos.

^_^

I colored it a bit.

I added some more details to the trees. What color should the sky be? (I just colored it so I could tell the sky and trees apart.) I was thinking the sky should be a misty color.

It took me about 40 minutes to do the tree, So I wanted to get your 'OK' before continueing because it would be hell if I had to erase the -whole- thing if I spent 40 minutes a tree. ^_^

Grass. Yay.

I tried to color the other tree so it could kinda match yours. I also messed around with the bush.. O.o; I can't color bushes, haha.
Very nice job on the grass! I can almost hear the breeze gently rustling through the blades of grass!

I'm afraid I've taken some liberties with the unicorn and the bush, I wanted to give the unicorn a suggeston of a coat,I hope I haven't ruined it -_-
