Here's a HG GM II I worked on earlier this year that I entered in two different local competitions, I won a HG Jesta in one and HG Aerial in the other. I usually spam preshades on all my builds but its always just light colors on top of black or lighter colors on top of the same color (light blue on top of dark blue). This time I used green as a base coat and a mixture of yellow+white+green as the post-shade and it really makes the colors pop, makes all my other preshade builds look dull, I feel like my eyes have been opened to a new world of shading
