hope you threw it back in the water after taking the shot ;) I like the angle its interesting along with the crop and feeling of the sun .. nice work :)
May be a different angle could make this more interesting... You know, the colors and the lighting are just perfect, but I see a very... dull and common angle...
You have cut of a tentacle: which is a very sad thing, too bad. Cutting of little pieces of persons is a stupid mistake to make as a photographer, mind this in future photographs!
5 - Looks like good potential with the colors and natural sunlight. Criticism; sharper, the 'arm' not cropped/chopped and a little more space perhaps on the left/bottom make this even better in my opinion. Good 'find' in a seemingly natural environment. Yes they are 'animals', if interested some more info: Answers.com on Starfish (Sea Stars) Kingdom: Animalia, Phylum: Echinodermata, Class: Asteroidea and from Enchanted Learning - Sea Stars"Sea stars (also known as starfish) are spiny, hard-skinned animals that live on the rocky sea floor. These invertebrates are NOT fish; they are echinoderms.
Diet: Sea stars are carnivores (meat-eaters). They eat clams, oysters, coral, fish, and other animals. They push their stomach out through their mouth (located on the underside of the sea star) and digest the prey. Anatomy: Most sea stars have five arms (or a multiple of five) that radiate from a central disk. Sea stars do not have a brain; they have a simple ring of nerve cells that moves information around the body. Eyespots (primitive light sensors) are at the tip of each arm. If a sea star's arm is cut off, it will regenerate (regrow). Classification: Kingdom Animalia (animals), Phylum Echinodermata (echinoderms), Class Asteroidea (sea stars), about 2,000 species. "
Nice color and interesting subject. I'm not sure if I love this angle of view. I realize it helps the viewer see the star shape but it looks a bit flat to me. I would suggest a much lower angle of view to capture the light slanting across the starfish which would bring out more detail in the texture and heighten the drama a bit. It also solves the problem of the photographer casting a shadow over the subject which looks like what might have happened here.
