The only thing I'm really not feeling is the word 'ecology' and I'm not sure if it's the word itself being present or the color. It seems like it would look better if it was a color different than the ones used in the design. It makes the rest of the design's colors look limited to me, like you only had 5 or 6 colors to work with-- and I didn't think that until I noticed the writing. But I think the actual design works perfectly!
