the y recieved a good basecoat of dull black, then i went over it with GW Mithril Silver drybrushing.
i had to mix up some paints to make sure the yellow i paint on is close to the base plastic color. i could have avoided this with just paintmasking off the parts but i'm not really that cool with cutting and sticking templates of masking tape on them so here's the results so far:
on the left you have the unpainted shoulder left in the plastic color, and on the right you have the painted, nacho-cheesy colored head of bumblebee.
...this might take a while.
