Don't worry, most of us go through it. My armor sat in a box for about 3 months. Just take it piece by piece. And watch Trooperbays video tutorials. You can't go wrong there.
Looks good. I'd suggest for the chest to do more of a big blotch pattern to be the vocal weathering for the chest. Look at the screen armors to see what I mean. Most have a distinct large blotching on the chest. Just gives it that iconic look.
Have a boba and vader on my forearm, first order tie fighter on my wrist, imperial cog on my elbow. And a huge tk piece on my bicep. Still need to finish it.
