Here it is. A truck-load of Floro Dery artwork from
his blog and his
Etsy "FDartstudio" account (many of these are no longer available from there but were mirrored prior to their being sold). All of this is mostly from season 2 and season 3 of the G1 cartoon, the G1 movie, and some early/unused concepts from either:
Decepticon Hall of Heroes, shown in BG are the Earth's moon and the severed head of Unicron.
First version of Junkion spaceship, in BG is Cybertron.
Temporary Decepticon base, in BG is Cybertron and two of its five moons.
From the episode "Enter the Nightbird"
Shown on the left side is the Decepticon Forest Base; on the right side is the Decepticon tower on Cybertron, in BG are three of the five moons of Cybertron.
First is from "Make Tracks", and I'm not sure which episode the tower is from.
Decepticon lunar dome base.
From "Blaster Blues"
On the left side is Cybertron and its robot mode.The city of Lithone, in BG is Unicron, is on the right side.
First is from the discarded early draft of the G1 movie called "
The Secret of Cybertron"; the second is from the final version of said movie.
Early version of Autobot City, from when the name "Fortress Maximus" was originally going to refer to said city instead of being the name of the big Headmaster Citybot.
The first version of Fortress Maximus, shown above, transforms to Autobot City, shown below.
