The natural next step from my G5-to-G1 designs: G4 to G1! Since these have been done to death and there are a few G1s considered "equivalents" (Applejack is literally in G1 as-is), I decided to take another route and use this design challenge to incorporate lesser-known G1 lines :)
If you want to see another between-gens type of redesign, send in an ask! I might futz around with G2 next!

Oh my gosh, love the thought behind each design and the art, they are lovely!
