The current LH gunship just needs a slightly more streamlined model. Nothing fancy, nothing big. Maybe elongate it, and give it a few more aerodynamic curves, but keep the shape relatively the same.
Well, my opinion regarding the current LH gunship is:
1.Its brick wings looks like wafer to me. (Each of them probably not a wing, but something else). Please make them look less wafer and add a bit aerodynamic to them. But keep the brickiness, because the gunship will turned into a snub if you change its brick wings to real(less brickie) wings.
2.The black part of its brick wing reminds me of a wafer cream. Please make the black part of the wafer more detailed, so people will easily recognize that the black part of the wafer is not a wafer cream, but a bunch of exposed electronic components of the ship.
Overall, the ship looks nice and only few tweaking are required(texture included) to make it even better.
