A cool green and gray space fighter I made just yesterday. It has 2 plasma missile launchers on the front, along with a small laser cannon, and 8 shrapnel cannons under the engines(four on each side). It also has an opening cargo storage thingy behind the cockpit.
It is very good compared to your other mocs, what i would do is try rebuilding this but start off with your green, by making a solid strip. Try to also taper the nose and rear section of the ship to give it that bit more shape.
Otherwise very good.
Looking at your other creations, you seem to be able to build interesting models, and this one is no exception. The overall shape is very unique like your other models, but it also has color and smoothness problems. If you can find a way to eliminate more studs, and match colors correctly, I think your models would be top-notch.
