Lemme sneak in a quick custom between Ratbat's posts here...
Yet another Starscream. I was sparse on the details on the back. I didn't want a full blue tail, but I didn't want it too boring either.
As for insignia, I REALLY want to put transparent ones down instead of chrome-backed, but I don't have any and don't really need an entire sheet from reprolabels.
And the robot mode. I painted the panels the arms attach to, as well as the sides (leaving a section alone for the 'belt'). Plus, I painted up inside the helmet where it meets with the faceplate.
Better shots of the sides and under the arms. Repainted the vent housing on the shins. I also left the legs in a two-tone, since the vynil spray coat didn't want to grab the harder plastic of the upper legs. And the two-tone doesn't look half bad. Plus, leaving the guns unpainted will give the second tone a little more presence.
I don't think I'll be doing any other details, except putting the symbols on.
