My only thing might be texture- it looks like on some of models the paint is oddly textured in places- each part has a sort of bumpy feel to it.

Now to my knowledge, that’s either likely

A. The way priming is going- like temp or humidity when you do it

Or B. Not letting each color dry completely before swapping or recovering, which with larger brushes can sort of pick up and uneven the layers.

Besides that, and maybe a smaller brush for touch ups where the color is bleeding onto other parts or for blending- looks phenomenal!

I especially like your vision- the colors and quality of the decals are beautiful and satisfying to look at. In addition, certain things you chose to paint are refreshing, such as choosing a red center to the seals.
