I agree not putting it on white; silver or maybe a light blue would work. Also agree with the idea of giving spring buds instead of leaves, since right now it looks like you have two autumns going on.
thanks for all the feedback. the addition spring buds is an awesome idea. the original design actually included stars, moon, sun, and a mountain range, but the 5 color limit drastically changed the design. i'll have to incorporate the buds and see how it looks. maybe i can submit it with buds as a general submission after the contest is over. these are my first two submissions threadless. i can see now how the critique submissions could be very helpful in fine tuning your design. to be honest i was shocked at the amount of feedback i have received. this is one of the first "social" sites that i have belonged to ion which the community is actually very active and willing to help in the creative process. :)
