I have been trying to upload my T-shirt design to the Threadless forums to see what needs to be changed before it's released, however for some reason it won't allow me to post a new thread so i will try here instead. This design i made was literally about 10 minutes work and has an Adventure time vibe to it.
These are the main problems i feel might need to be changed/added.
*Colour of background (is the orange okay)
*Any texts or quotes to say underneath
Design 1:

Design 2 (changed the pupils):

Sorry, the website i was using wouldn't let me upload thumbnails.
IMO the second one is the best look but i will leave that up to you to decide.
