Hi guys. Drawing sprite is my hobby and I want to use it in my game. Here is my attempt in making a fish sprite. However I always feel it is not right. So here is a few questions that I would be very happy and thankful if they are answered:

What is the right resolution for game, on mobile may be? I never feel that my sprite is pixelized enough.

What style of the four ones looks suitable for sprite? The first one does not look pixel for me.Please help me improve it.

Thank you, guys.



Here is the animation
