Ok, I see what you mean, I will repeat some frames an the end. The arms move up and down very fast while firing, along with the back and the legs a bit. I could make that motion to be more evident without zoom, but I would not want to exaggerate it.
The guy in the original sprites holstered the weapon to the left, and then it suddenly disappeared , like if he put it into some kind of magical pocket. So I had to change it, but I could not make it holster to the left, so I made it to the right and from there to the back. Maybe it should have some kind of harness when the minigun is equiped or in the back.
I sure could add some muzzle flash, but It would not look very good if it is just geometry, also it would not be lit in the dark. If I had alpha and luminance map support in the engine it would be great, but I would need to compile a shader and I don't know how to do that
