I think the lightning is fine. Are you manually focusing? If you had not cut the flower off and got your focus in order, the image would have potential.
Yeah, it's a step in the right direction. Also, again stop and think about overall composition. I see that PCFiend took my comments about framing on the previous photo (tighter shot, flower on right, leaves on left) and applied it to this flower shot as well. I'm not sure that was the best composition for this shot, as the flower is different (MUCH more complex, odd looking) and the leaves are totally different.
In the previous shot, you had a few branches of leaves with water droplets, creating a bit of a line, and a little bit of interest from the droplets. Enough lines and interest to fill balance some of the negative space and lead your eye to the main subject. In the new shot, the leaves are just sort of a neutral background, so devoting half the picture to them might not be the best idea.
Again, the "rules" of composition are anything but. Unfortunately there's no guide to "how to get the best shot of a flower with one simple click". You have to think about each subject individually. The GREAT thing about digital, though, is that you can take a billion shots and check your composition, exposure, etc. as you go along. Or try different things with the same subject. Unlike film, it costs nothing. You might only keep 1 in 20 images, but that ratio will get better as you shoot more.
