Vector Rosebud

This is my very first 100% Mesh Tool piece. It was an intense labor of love for me, and I enjoyed every minute. After seeing so many realistic vectors out there, I had to try it myself. I have to admit my pride, the mesh tool exceeded my expectations. Since I'm still a noob, I would appreciate critiques, or even just a few words on how I could improve.
