I see what you mean Chirone now you point it out. I was trying to keep the same feel of an industrial, mechanical look over the whole model, but the wings do look a little fragile.
I have been back to the drawing board and come up with a new wing design which is moulded over the top of the hull. This did present new problems with a smooth moulded wing attached to a very square hull. So I look over that design as well and changed it a little. From doing this I have come up with a few variations on the basic design.
1. A Large Troop transport/Cargo ship
2. A fast, light scout ship
3. A small one man fighter

The first 2 have a very similar design, while the fighter has the same moulded wing design over the hull (and looking a little similar to the Z-95 Headhunter)
I’ve made a sketch of the basic design in Maya to block out the basic shapes.
I will continue to develop these as I think they are better looking designs.
It’s not quite starting again, as a lot of the external pieces, I can re-use on these new designs and all the internal parts I’m happy with and can moved then on to the new models.
