This is my take on Shattered Glass Starscream: NOTE: this was partially inspired by Split Lip's Animated SG Starscream
I based it off Split Lip's drawing which was inspired by Armada screamer, but now that you mention it, he does look like Hot Rod.
So now he's HotStar? RodScream? StarRod?? I think that the colors suit him pretty well, nicely done! Just one nitpick...maybe it's my eyes, but I keep seeing shadows of blue here and there?
I prefer the official, but for less of a SGCyclonus/rodimus vibe, try swapping the grey and yellow locations on the robot, retain the yellow stripes, but keep the gold/ locations.
