Nursery theme?

So we just found out were having a baby boy :) i had a feeling it was a girl so i had ideas for a girl nursery and not a boy one.. I know, i know, i screwed up. Now that its time to get everything ready, i have NO clue what theme we should do.. Ive thought of disney themed, and toystory themed. I fear that there will be too much going on in a disney one. And ilike the   toystory idea alot but the nursery is so small that i dont really know what we can do.. We havethe crib   and change table (dark brown) but i fear we wont be able to get enough themed things in and it turn out half ass.. Suggestions? Im freaking out.. The pictures show how small the room is, and we dont have a dresser yet, thats why theres stuff on the change table..
