Could I have the same comparison of size for the VHF with the guardian on top ? From the image you gave, it looks like you made it a bit too small.
Except this size feeling problems, the model itself is very well done.
For the war ships, I would say the LN warships would be better. I mean there is not so much hackers, I don't think the HF have magic hands so making big ships from nothing should be out of range in fact, but stealing some is a possibility.
I mean here that you should stay very close from the LN war ships.
And the GB is ugly (sorry but that's my point of view), maybe the textures you used. I prefer the LH GS:)
