OK. #1 exposure is wrong and the background is just way too busy. Steals the show. Use a longer lens. #2 is cool but perhaps could be better if you had the "ribbon" running diagonally through the frame and did not include the water at the top. Make it all one pattern. #3,4 get rid of the snail. Anything lighter than the subject can be a problem, anything more round then the subject can be a problem. It drawing our attention away from your intended subject. Gene
