Very good style, especially for a painting, and a strange mixture of colors as well! However, it wouldn't be very provocative of me to not point out that a particularly large grouping of fish can only be considered a "school" if it consists of 10 to 1,000 individuals. They will typically behave this way to form a large cluster that is intended to frighten predators. But hey, who would want to eat a fish skeleton? Plus, this is just art, so it's for the best that it's purposely inaccurate. P.S. the middle one is the best! :P
