I have to agree with the rest, that they're a bit too colourful and the current Coalition ships look better.
Here is a summary of my opinion, I tried to include as much constructive critisism as I could. (Not trying to insult anybody).
Texturing:
The hammer logos and stripes look rather ridiculous in my opinion. Why bother with fancy logos and stripes, if the ship otherwise looks like it's made out of spit and twigs?
They do not enhance the ships abilities in any way, and in the middle of combat you wouldn't really pay attention to them anyways. (Or even see the logos that is).
Making their tools of war visually pleasing fights their nature in my opinion.
For example this is something Kusari would do, not Coalition. If you catch my drift..
Otherwise the textures look good. The cockpits especially.
Models:
The models are decent. I like their shape, though they could use a bit cleaning. (The top mostly, looks horrid).
In my opinion the light fighter is the best of them, rest two look rather messy.
I don't like the fins. After all it's space, where would you need those?
Not only do I find them unnecessary, but unfitting as well.
And like I explained earlier, adding them just for visual is not something Coalition would do.
Also I don't like the green/yellow/black engine things neither or what ever they are. What's the purpose of those may I ask?
Conclusion:
Messy models with partly unfitting texturing.
I would give these ships a score of 6 out of 10 points.
