We like the gunboat as is. And personally I find it few steps up from the LHGS that I find to be ugly ("sorry, but thats my point of view").
The VHF might look small, but the "Guardian Spolier" was taken straight off the Guardian with no modifications (if that gives you an idea as to the size being what it should be). Quite honestly its also a bit easier to hit than the Sabre because its holes aren't as big as the Sabre's.
Great job on the model, too.

Must make small 4.85 and 1/2 Patch to get the HF Ships in ASAP.
