Hi, redname.
Thank you for sharing your works. The clown fish (pardon me if I ID-ed this fish wrongly) is very amazingly cute. Quite a good capture, isn't it?!
The first three photos - YXTM and the two guitar shots perhaps you could adjust the White Balance as it is a little off, too green. Sometimes I find that even when I switch to the supposedly appropriate WB setting on the camera, the end result still turns out a little off. So no choice, have to adjust with post processing software.
Hey, just a bit of my humble opinion here.
