FISH!

Hello there, I am new to this forum and I have been fiddling around with pixel art during the past couple of days and decided to start out small with some fish/creatures to find to right sort of fit for me. Here are three sprites I did while attempting to get a similar look to another fish. I will admit that they are pretty bad but I would appreciate some feedback as well as some pointers to guides to make them better, and if anyone wants to give them a small touch up to teach me a thing or two I also wouldn't mind. I only attempted to shade the first fish since I feel as if they were coming out a bit "wrong". I want the light source to strike from the top. The green fish seems to have a bigger pixel size which in my opinion makes it look more blocky but whenever I try to set a larger pixel on grafx2 the pixels do not align into a perfect row or column, they intersect and create 1 pixel gaps.



The kind of look I want to go for
