Looks good to me. If you’re trying to blend the two, I’d start by thinking about what the purpose of the suit is, who uses it, and when they use it. A OYW Zeonic suit will be more specialized, while a Federation suit from the same time will most likely be more general-purpose. You can then guess about its weapons, what it’d fight, the reactors, what parts it uses, and a ton of other things.
For example, I started my custom suit, the Streiter, by blending the Kampfer and an ordinary GM. Then, I did some rough art.
Next, I determined that it’d be a Federation mobile suit developed from stolen Kampfer prototypes. That led me to equip it with a pair of Beam Spray Guns, two Federation-type bazookas, and an extra pair of knee-mounted beam sabers. The Federation didn’t have much need for a colony attack suit, so I made it a ground type, meaning that in the later art I eliminated a few of the verniers.
It’s a process.
And here, I made all of the colors match.
