Final render:
please critique.
Looks awesome, one thing: i would move the middle one forward a bit. i dont know, thats what i would do.
Your modeling is very nice, the big thing that strikes me is that your materials on the missiles feel more like styrofoam than painted metal (unless of course these aren’t supposed to be real rockets, in which case you nailed it). Making the material a little less soft and maybe adding some rivets and doing a little decal work would make a big difference. I’d also thin out the fins a little, and/or round off their leading edges. You’ve got a really nice start going here, I think with just a little more work you’ll have something top notch.
