I mena you have tubes for the barrels of the weapons that are what, 32 sides or something, that are then hollow as well? Your looking at a lot of polygons there, when you could simply do a 16 sided tube thats solid and just texture the end correctly and nobody would tell any different.
Your proportions are off, the face looks squished; I think you might be making up some of your details, and not putting details in the right places. I would go back and try to find as much reference as I could. http://www.thelightworks.com/models, http://www.thelightworks.com/models/img/models/atst_ss_02.jpg,…
It's not really meant for anything mate, Just been modelling it in my spare time, "You have really dense, hollow tubes for the turrets all over, when they could be simple tubes, none hollow, with a texture" what do you mean by this mate?
Ok now the pics are showing up, I'll offer a few quic points up before dinner... Nom nom, take away... Is this an ingame asset, or a static portfolio piece? You don't offer much in the way of info for it, so we can't really say if its too high or too low detailed or what have you. I'm gonna go with it being a low poly…
Take the "S" out of your URL at the start, http not https. Alos, post a bigger picture thats not driectly from milkshape (It looks like that anyway), with wires on one too, because atm you can't see anything other than a grey blob.
