Love that first shot! Keep an eye on your horizons (oceans are especially noticeable if they aren't level.)
A few aren't in focus which can really kill the whole shot.
1. I'd have liked te girl to have been a little smaller in the frame so as not cutting arms off but I like the image.
2. Is a tad under exposed but a great snap
3. Watch that you get the eyes sharp - great expression but the focus looks to be on the top of the head.
4. Looks under exposed but nothing that can't be lifted in post - look at the histogram. Central composition doesnt work either. Set off to one of the thirds.
5. Another image that would have been great had the eyes been sharp. Nice light and handsome model but the blurry face loses it.
