i for one would feel a lot more comfortable with the ship, if the 3 guns would be just a bit bigger than the 2, and also a bit shorter, they look quite out of proportion right now
i think at least the opening of the barrels should not be that big
The three guns are bigger, the've got 816mm diameter barrels (interior) compared to the 620mm diameter interior that the two other guns have.
Also the guns are actually shorter than the retail ones. However I do see what you mean, so I added a support to the guns near the end, I think it helps.
https://p3d.in/sRuEaAs for the details, everything is in fine order. However I would strongly suggest to get the angled engine pylons back. It distorted the whole rear section and width proportions. I find it very weird at some angles, especially this one:
(though I understand the point of making them straight. First thing which crossed my mind was the engine thrust. Force distribution would be handled better with straight frame then angled one. Or was that only esthetic reason behind it ? ).
It was for three reasons that I changed the pylons to be straight, a) aesthetic reasons, I think it looks a lot better with them straight, b) engine thrust, and c) it makes the Ursa look like it helps form Voltron
It's surprisingly low on greebles for a Hades(tm) model.
Being on WoD and making models for it helped me learn to temper myself a bit and I've grown up a bit as a person, so I no longer just look at models and go full on detailing mode.
