I never intended on being non-welcoming (Actually I never intended on even posting in this thread. But I do like a good discussion.

), and I know the thing about people not explaining comments was not directed against me, I just thought I'd put what I do in there.
I do see your point with the extrusions, which I quite expected to get after I wrote that message but what I meant was that by detail I'd think that more precise details instead of just extruding once and scaling it. I know that a lot of the things in 3D is based upon extruding but I wouldn't phrase what he did on the barrel area as "detailing" for say, more of defining.
So basically I just get hung up on the actual phrase "detailing", as for me, that means something a bit more in depth.
People seem to call something a cardboard cutout when a larger part of the model is flat along the Z axis, this model not really being a cutout in my opinion (I know I am sort of being a hypocrite here since I said that I thought it looked like one, but hey, opinions change.) more of just a gun model which has a little bit too flat body.
And yes, this model would look good with a little bit of tweaking and tinkering to remove some of the general flatness of the sides by (Again) either just beveling some edges; though it being slightly overkill on a model such as this and will add a lot of unnecessary polygons, or by, as stated previously, just taking the edges next to the center Z loop and pulling them down a little bit.
@Game Master:
It's not that no one likes it it's just that people like to critique models here, good or bad, no matter what you post there will most likely be someone who thinks that you can improve in one area or another.
The comments we post are really just for your improvement in this area, so that you can take our advice in mind the next time you make something and therefor making something better and improving your skill.
"Removing this thread" would be over the top in my opinion, just be ready for some criticism, as people here like to fire it through machine guns right at you the second you post something.
