Death-Ray Sunflower

I am currently working on another book cover and need to model some "aggressive vegetation." This was my take on a sunflower that tries to incinerate anything that comes near it by reflecting and concentrating the sun's rays. This was just a little test render to see how I liked the materials.

If you are interested, you can see me model it here: https://www.youtube.com/watch?v=iOK-sHe7CaE
