I particularly like the lighting on the second one. My personal preference would be a closer view / tighter crop. The focal point for me is the center of each bloom. Making those a stronger part of the composition would be nice.
As is, I like the lighting on the 2nd one better, I like the glow from the backlighting on the 1st one, but it needs more fill in the front to balance it out. I also like seeing the stems, if only just a bit, so the blossoms aren't just floating in space. That's just my opinion.
The illumination behind the white one is nice, but it seems dark on the front. I wonder what it would look like, illuminated, with a black background, if you can work that out. I would like to be closer up to the black backgrounded one, but the lighting is very nice.
My other thought is, "Wow, your taking shots like this at age 14!" Then I think, "Oh, wait, I'm only 16."
the second one is really nice. As per John's usggestion, I would crop it a bit tighter.
BTW, I checked out your prints & they are really nice as well. Just so you know, you have a small typo in your bio/message (available is spelled as 'availible'). Just thought you might want to know.

You could tweak the lighting a bit with the first one, but I love the backlit effect a lot. the second is more traditional, and I like it too. I actually like it with the negative space around it. Cropping it would take some of the mystery out of it, IMO.
