your an amazing painter

......but i'm going to throw some suggestions at you.......some
thing i read, and have been taught.
when planing a paint scheme . (be it graffitti, canvas ,mini's all part of my hobby's ) plan it around 3 shades or colours
on your krox you have 2 shades. The blue / sky blue and the gold / bone
by adding one contrasting colur it would bring the viewers eye to attention on one area before looking over the rest of the model.
you have kinda done this with the krox's eye using green
but i think that for myself that third tone or differance is what is missing from making this great mini even more amazing
but i'm no expert here.and it is risky having to much colour happening on the mini
but the rule of thumb is less colour is always better and you have made this min great buy sticking to a simple scheme and painting it well.
