Looks awesome. This is more along the lines, I think, of what the "Shattered Glass" line should have been.
That looks really good! I never noticed how good of a head that tank Megatron has, since I never liked that version of Megatron. Only change I would do is add a cloak like DotM Megatron (maybe purple with the Decepticon symbol over the shoulder?).
That is an excellent custom. Love it... all though I'm not quite sure what's up with his crotch. Megatron is hung.
neat! very clean work on the add on peg holes. i like the headsculpt proportions, the paint apps, it all looks fantastic!
nice work i have to agree with a previous previous user on the silver altmode, a stripe or mayby diferent colors on the grill and windows will go a long way
