My fav is middle piece I really like your style and I also wanna say welcome to the Void

ALways happy to see new memebers show off their master pieces

These are really nice work,

My advice for the first stock with the mountian is play with the layering adjustment in your layer tray (the black/white half moon) The very bottom option is called "selective colour" click on that and you can try and manipulate the green out of that spot on your sig

Hope I gave you a helpful tip ^^

Welcome to the Void <3
