I can't believe I actually "captured" one of these little guys! Usually I manage to scare them off. I used the photoshop clone and smudge tools to take out a cob web, I think I did pretty good!
I like the perfect focusing on the bird. And the light coming from right is great.
Unfortunately, your DoF (Depth of Field) is to tiny and the flowers are a little out of focus. I don't know which cam you own, but, if you can, you could use the aperture priority, give a ± 8 value to increase the DoF.
Last thing: maybe you could of-center the bird (the famous rule of third...). Hope it helps :-)
wonderful job on the photoshop work. not sure where the cobweb even was! the shot looks completely natural. i do wish, however, the hummingbird was a bit closer but i still think the shot looks great! well done!
