Birds, birds everywhere....

I have been working on a project for my daughters room. The goal: A finished mobile of fabric birds and branches. I found the idea here: SPOOL and also got a free pattern which worked like a charm. I made a few minor adjustments. I found the greatest family of fabrics at IKEA and have also made curtains for her room. But I just can't seem to finish it all and make up my mind on the color of branch. Ridiculous thing to stew over but color is the kind of thing that would literally drive me crazy if it's not right. Maybe you can offer some suggestions? The idea is below and some not so great photos from my camera phone of unfinished birds.(close but a little work left to go)

I'd like to paint a tree on the wall similar to this: TREE and cut out fabric leaves from the family I have been using. After cutting them I'd like to adhere them to the wall and then hang the mobile close to the tree so it looks s if it is coming off of the tree. Now for the color dilemma. The Buggaboo's room is white and blue so the tree would be white on a blue wall or green on a blue wall. I just can't decide...but when I do you'll get a finished photo. I swear my life seems so busy right now that it probably looks like I never finish anything. I promise, I do.
