Sharing the opinion of the recent posters, I am very impressed with the work being done. Signing what Boguslaw proposed before me, I'd like to add a few extra suggestions. They are all minor which reveals how close we really are to a final model that can then go through texturing and get a proper size compared to its main rivals which undoubtedly are the Guardian and Manta.
Except #1, the rest of the suggestions are mainly trying to address the bulkiness appearance of that VHF model, which even though they do not provide any real advantage ingame, they make it appear less bulky.
The windows should extend on the right and left side of the cockpit.
The "bridge" connecting the cockpit with the ship's main frame can be much more narrow. In the image I propose to cut only a small portion of the existing "bridge", but I think it would look even better if you cut even deeper.
Another small part that can be cut. A deep but very small cut which creates the illusion that the ship is less bulky. Especially important since its on the back of the vessel.
I really like the wings. Their small and unusual shape. I'd like to show off this characteristic more by slightly "pushing" inwards the parts of the ship which hide the wings from a front or rear viewer. The parts should not be removed in favor a straight line of course, I am asking instead to be pushed slightly inwards.
