I have been using blender for about a year mostly for vfx and motion graphics, so is my first real render. I was inspired by the BlenderGuru tutorial, and decided to make my own pink flowers. I chose to do the mimosa tree because they are in bloom right now around where i live. I would appreciate any feedback.

Congratulation 
Cycles rendering ? Or BI?
It is rendered in cycles and the lighting is entirely from the hdri environment.
beautiful 
add a little bit textures on the leaves and make them translucent
