First off, I'd like to say that these images are a great size. Very easy to see.
The sky is gorgeous in all of these pics, must've been one really nice day.
My favourite is the third one, it's the most unique, and interesting photo.
The first one is a little slanted, which makes me feel a bit dizzy - especially seeing as I don't really have a main part to look at, so my eyes are just wondering around all over the photo. So, you could work on the angle. I'd also consider cropping out the sign and the blue thing on the side - they don't really add anything to the photograph, and they just distract the viewer.
The second one is pretty cool, and I love the way the light is reflecting off the ocean, and the sky is just gorgeous. Maybe you could work on adding a bit more to the photo, it's nice, but it's a bit unoriginal. Maybe you could mess around with the angles, or find something cool to frame your photo around.
The third I love - it's very unique, and just an awesome photo, two thumbs up!!
The fourth is a little boring, maybe you could enhance the colour to make it more like the lovely blue you can see in all the other photos? Also, it might be fun to find something interesting to frame your photo with/around.
The fourth is nice, a little empty, but nice none the less. Muck around a bit, have some fun, see what you can come up with.
Good luck in the future, keep posting.
PM me if you have any questions, or need me to explain. I'm always happy to help. ;D
I'm no photography expert, so don't take my critique too seriously. I may not be an expert, but I love these pictures! And I love the beach!
My favourites by far are the second and the fourth photo. In the second one, I love how you've taken a photo of the beach with someone walking across it. It looks really effective!
In the second one, I love how the water glistens. I'm one of those weird people who love water, so that's another reason why I like your photo! I really like the ripple of the water as well, it looks really pretty.
I haven't really got anything to critique, except for the first photo. This is just my personal opinion, but I think that the sign and the blue thing in the picture kind of puts me off it. If you'd cut that out, it would be even prettier! Don't take this too seriously though. Like I said, I have no idea about photography
Overall, I loved these! I'll definitely be looking out for more of your photos.
Hope you enjoy them! -Z
Very easy to see.
