Thanks for all the great comments! Alas this shhip has been torn apart, but i might rebuild it one day. Also at the time, I had no more tiles to do the wings with. Happily, that has changed after my recent Lego.com purchases!
This is a tight little craft. Compact, well armed. It looks very economical. The only way I can thing to improve it would be to cover some of the studs with tile. Even so, it already rocks! You should build a simple 16 X 16 landing pad, and park it on the pad so you can enter it in the Metal Legion contest. This thing is very competitive. Attack!
