Some minor and mayor problems. HELP ME! ;__;

Hi guys

so I redrew my earlier picture and I like the new version. But there are some things I'm struggling with.

  1. It's the first time I'm using Kienans technique of sculpting. And I have no idea how to draw hair that way. It looks like total garbage :( Any tips?
  2. Weapons in perspective..... I mean... how? I tried reference photos but they never have the right angle for me
  3. Any ideas how to come up with a simple to draw but nice looking background?
