Hey Daniel,
The canvas is a good idea for its texture.
The rose is a good idea for its beauty.
The shadow is a good idea but in a other approach.
The greatest asset of this picture is your treatment of the flower… very cool!
I can imagine the rose resting on the canvas and a very soft shadow revealing
the texture of the canvas… all in the same treatment used for the second take!
I will not call this a homework… but you have something to explore. ;-)
