Apply the following layer effects:
- bevel: shadow = black, opacity: 10-15%
- outer glow: black, 15-20%, 2-3px

Duplicate this layer, rotate, resize...

...repeat, repeat :-)

Our flower need special leaves for it too. You can use the original layer you created for a leaf in the beginning of this tutorial. Duplicate it, paste in the layer under flower layers...

copy, paste, rotate, repeat :-)

Duplicate layer, rotate, resize! (I also made shape color a bit lighter).

Another part of flower - in new layer, draw a curved line using Pen tool. then - surprise! - copy, paste, rotate, repeat!

The flower is ready!
