Instant fan right here!
With some work, I might be able to recreate those using Fall of Cybertron's character customization.
Very good looking futuristic alt modes you can see each with a nice windshield and respective wheels!
protectobots had 5 guys didn't they ?
Hotspot turned out really cool here.
Ah, well those make sense then, at least as much as any of those from that aesthetic do...
Really like your concepts for their alt modes.
I own only three Transformers. One of them is a van, a bit like your First Aid. I wish I could buy your First Aid. As a solid model, of course.
I like their robot modes, though their vehicle modes could stand to be redesigned slightly, if you ask me. Otherwise, the shading is pretty impressive. On another note, do you intend to do Groove and Blades, next?
This is hot and you just keep on cookin' up the robo-sweetness!
