First of this picture is absolutely stunning. The focus you used, the composition and everything is great. You picked a very beautiful set of flowers to photograph for sure.

The only thing that's off to me is the two pieces of grass along the front and side of the picture. They're distracting and maybe moving them out of the picture during the shot would have helped out a little to make the picture a little less busy.

Outside of that this picture is very lovely. Your use of the rule of thirds, color, composition and f-stop show very strongly here. You're well on your way to being one of the greats of photography. Keep up the great work!
