Weapons I'm working on

Wolfer

Hi there so this is my first post here and I hope to get some friendly advice. Kinda nervous.  I working on this weapon that is going to be a sci fi sniper rifle. Its takes places in the future and wants to see how it looks so far.  I want to see how the modeling is doing before I put in textures.  I see some things to work on but could use some tips to help me out.
