Thank you! Yes, the Discovery isn´t from Galen, but from Madeinjapan.
You pointed us some cool ships too. The Queenstown is, in fact, the Excelsior-B, designed and built by Tachy (Cirylle Lefevre) looooong time ago. I still have that mesh, and a Lightwave conversion is available online:

About the one from Skye Dods, I´ll talk to him and see if there are news.
I should be thanking you! A lot! You have posted a treasure trove of ships that I didn't even know existed, and even managed to post images of one that I've had very little luck of finding close up views.
And I'm very glad I could help. I'm sure it must feel pretty good, getting introduced to ships that you didn't even know existed. I'm certainly loving it.
And I'd appreciate if you can get any more information on the Explorer/Chimera, especially if there are any more images I haven't already seen.
Oddly enough, there is a very similar design intended to be the Zodiac-class, one of six designs proposed on the ASDB site, but the final design was never chosen before activity ceased.

Status: Unsure, but it looked close to complete, however, the mesh was never released publicly

Great minds thinking alike! that was shortly after I did my Grand Alliance:

Never mind your ship was so old too.
In fact, from Starfleet´s point of view (if I can say that), Nee´s version looks like a previous version, and yours an evolved, updated version. I say this cause the naceles design. Both ships looks cool, but I think the flipped naceles configuration of Nee´s ship fits better with starfleet standards.
Ah, but I wanted to buck the standards and do something unexpected!
Actually, I was gonna say his looks like the more modern ship - more detail and angles, like a post-TNG ship.
To be honest, I never did like the look of the flipped pylons and nacelles. It just looks awkward to me, and I wouldn't have changed the way the pylons were mounted.
I didn't give my two cents about any of the other ships, specifically the ones I've never seen before, because it would take me hours to do so, so I'm only going to do one at a time per post instead. First the Invincible.
From year 2004, the USS INVINCIBLE.

To me, this looks like she started out as a dreadnought version of the Sovereign class, but started to evolve into her own thing.
She reminds me a little of the Intimidator-class Dreadnaught:
