Rock Cannon WIP

I've been working on a Minigun model, this one called the ★Rock Cannon. (If you're familiar with where that's from, yay for you. If not, let the others do the cover-blowing)







I'd post the reference pics I used, but that would blow the cover of where this originates.

It should be noted that those pics are a bit dated, as I've made some modifications since then.

Don't say anything about the grips or the fact that there's a big space between it and the barrel. I'm focusing primarily on the barrel right now, and will work on the grip box thingy later.

I'd like to know, should the inevitable slit-spiral pattern be put in the model itself, or just normal mapped?

And about the triangles themselves, there's supposed to be a back curve on them, kinda like this. But pics like this make me think I should go extra wide.

And upon closer looks at my reference, it seems I got the tip of the barrel all wrong. Yes, I made the newer, more accurate barrel, but now I'm torn between which one to use.



Left is the newer, more faithful one, right is the older, first one.

I plan on releasing the finished model with a spinning barrel and without.

So, what do you think?
