Alright, well my only suggestion is that for photos of the sky, where you have that extremely bright light and faster shutter speeds - turn down your ISO (if this is possible). ISO is similar to film grain. The higher it is, the larger the grain. The smaller it is the finer (or smaller grain within) the picture.
Keep in mind that as you lower the iso, you need more light to develop it equally - so in the instance of darker areas, you may require a higher grain.
Your colors are superb on almost all of them - the 5th one down is a little yellow, and VERY grainy.
Aside from that, I love majority of them. Good job and keep up the good work!
PS. Love Myrtle Beach! You can see some photos I have from there in my gallery (wherever it went).
