First off, these images are waaaay to large, so I'd recommend you resize them. (Easier to view.) I can't view on entirely on my screen, they're that big.
Secondly, I've noticed, that they're quite blurry. I don't know what this could be down to (I'm not skilled in photography) but if the images were much sharper, they'd definitely look much better.
Edit: I see now. I had to click on them.
Other than that, keep practising!
