Wallpaper

This is the first time I use pen tool in Illus to draw. I intend to draw something like flora. As a result, I have this one above in black and white. After that, I paint some color to make background by using brush. And the final result is an image below. It can display on screen as a wallpaper. I use almost tool in Illustrator and I fix a little color in PS. Thanks for any comments for me !!
