Very nice! Keep it up with LR and RAW -- and don't look back! I do have a few suggestions. On the first one, I find the water drops on the left very distracting and would suggest you get those out. In fact, you can crop them out and get the flower off the dead-center of your image, which is easy to do non-destructively in LR simply by using the crop tool. (You may want to acquaint yourself with that trick for the fourth, fifth and sixth ones, too, since they also have the main object dead-center.) You might want to use the fourth one as a good one to for playing around with curves in LR. It could use some bump in the contrast, I think. You could use the contrast slider, but I think you might learn more about LR by trying to get it with curves. I really like the composition of the one with the bee because you don't have everything dead-center and the eye follows the first flower to the second one in the back. If you were really trying to get the bee, well, I'm not sure you made the little fella much of an object of the photo. But I still like it just for the comp. The second photo just doesn't do much, I think. There's a narrow band of focus in the middle but a lot of blur in the front and back. Don't know that there's much you can do with that one in LR, since it seems you were going with way too shallow a depth of field if you were trying to say something about all of the flowers. Furthermore, that one really doesn't give the eye anything upon which to focus. Keep up he good work!
