Wow Kup looks great!
Lugnut looks pretty impressive too,
Straxus is less G1 accurate but he does appear a bit more mean looking.
The others looks like decent molds, colours could be better but hey I have a paintbrush.
While I agree with the above the lines are blurring so much into eachother that It's diffcult to tell where one begins and the other ends, at least as far as asthetics go. these days I wait till I get the toy and then figure out what shelf they belong on, to hell with what Hasbro says.
