This ship uses the Enterprise series warship design that, for all intents and purposes, is older than the D12 Bird of Prey seen in Star Trek II - IV (Retired because they were likely to be as dangerous to their own crew as their enemies). It seems unlikely that it would be superior to the D12 / B'rel styled Tier 0 Bird of Prey.
Multiple engine exhausts: 2 on the wings, and 4 on the main hull. The two on the wings do not leave contrails and the two in the centre of the hull are over-under but the exhaust contrails are side by side.
Impulse exhausts should be Indigo / Violet
This is an ENT series-based model, a design older than the retired D12 Bird of Prey mentioned previously, sharing much of the design philosophy of the Tier 1. It could at least be more 'TMP/TNG' like the B'Rel / K'vort.

Canon Inconsistencies:Psi'a Meese points out some interesting on screen differences. Perhaps they should be integrated into ship costumes.
Forward torpedo tube texture is broken, rectangular, and should glow more
Aft section is entirely the wrong shape.
Impulse engines are the wrong shape and location: current STO (D7), Canon K't'inga.
Due to above, The aft torpedo tube is missing. Rear facing spotlights on fantail and bridge section missing.
Reactor buldge on the belly is missing (k't'inga feature, not present in D7)
Head is that of a D7: no bow flattening, bridge tower is level with bridge dome like a D7, should be taller.
The dome shaped neck bubble immediately behind the head where the officer's mess/lounge is located is missing.
Only two window rows in STO model, as per D7, Canon K't'inga has 4 on head, 2 on brim, 2 on head itself.
Ventral weapon pimple and beam bars float below the belly
Update K't'inga with Kronos One style model with actual raised armour plating
Struts need outer vent details, which should be maintained regardless of hull pattern.
Move fleet emblem from the top engineering hull to the struts forward these vents. Per the movie model.
D7 TemplateImpulse engine placement needs polish per remastered TOS, or removed entirely as the original TOS never displayed any at all.
Struts need outer exhaust vents.
Fleet Logo should be moved from the center portion of the engineering hull to the outer portion.
Add aft torpedo tube to mirror the one from the bow to make the in-game model more complete if the slot exists for it.
