awesome, welcome! I'm pretty new too. I got my camera like three days later than you.
I like your use of backlighting here to show the veins of the leaf. You have some good bokeh (blurry background). Also, I don't know if it was intentional, but shooting an odd number of subjects is usually a good idea.
Two things I'd recommend here. One, unless you're going to zoom in even more on your subject, don't center it. You really only center your subject in two cases: 1) when you're going for perfect symmetry (which isn't the case here) or when you're doing macro (and in that case it's more of a necessity, because usually the edges are a little distorted with macro and the sharpest focus will be in the dead center.
Here, I would have maybe moved a bit to the left with my feet, to take the building out of the background, and then put the central leaf on the left third line
