Alrighty folks - this model is more or less done at this point. I'd like to thank everyone for their feedback - I think it really helped this model along, and I'm very happy with the results. With the modified tracks - it now fits on a 80x70mm base.


Here's a parts break down - there's 21 parts in all:

I'd like to address some people directly now:
Evil and Chaos - Awesome suggestions, unfortunately, I was well into parting it out before I could add those additional details that I agree would look great. I will apply your suggestions on the next model. I also couldn't figure out a way to add details to the tracks while allowing it to be mass produced in resin casts (not without adding about 4 more tiny pieces). Again, I will focus on this aspect on the next model. Thanks for the constructive feedback as a fellow model creator.
Nitpick - Thanks for you observation on the tracks. There was something wrong with the front view but I couldn't pin it. Widening the tracks fixes this profile imo, and makes it look even more intimidating! This increased the base size, but I'm ok with that.
Again, thanks everyone for your comments - especially the size of the main cannon, which was reduced in size about 25% from the original design - looks much better now.
Now I've got to submit the model for printing "glup". A single sprue of hybrids costs about 9 bucks to print - anyone want to take bets on the printing costs for this beast?
