my friend the fungi

This is my first time posting here, I have been working with blender for a while now, and decided I should start putting things here for better learning and improving. anyway, this is playing with colour and the new (I just got it) partical/hair system, I made the background yellow, and added the border in gimp.
I am looking for any constructive crit, things I could do better next time, especialy concerning composition.

Well, to begin with, the color choice is(in my opinion) terrible. It seems to destroy the detail. I’d say try using a couple different shades of the same color.
