Well, I was modelling this for the (now probably deceased) HLP Model Contest Mk. II, but unfortunately I seem to have lost the model during a reformat (I was
sure that I had backed everything up) - so I decided to post the last remaining pictures of it here to get some public bashing and stuff. Maybe I'll even get into remodelling it some time...
It's supposed to be a GTVA battle tank. The main weapon is a low-power beam cannon (well, low power compared to capital ship beams), and the small turret is equiped with Maxim cannons. It normally uses the tracks during battle, in order to transfer more power to the beam cannon, but it's also able to hover at small altitudes. Two people man the tank, both of them inside the main body - a pilot and a gunner.
Here are the two pics I still have of it:


They're from early development, but since the model's lost, they're all I have to post now. If for some miracle I'm able to find the model, I'll post more pics.
