I really like the coloring technique! As to sticking with one technique, I haven't seen your others, but it's always fun to have a variety.

Very cool! The composition works well. The vine leads your eye all around and the rose is well keyframed. Her face and hair are absolutely beautiful. My only complaint would be the hands. Her left hand looks a little big. The guys hand is very well drawn, but looks a bit disconnected from his body. It's almost as if someone else is reaching over his shoulder holding up the rose. Very good though. As always, you do an amazing job with the eyes!
