Blender Experts lend me your ears!

So yea… I’m trying to be different some would even say extra. But I’m playing around in blender and I think unseenkiller mentioned something about skin packs? I want to add some scales on the upper and handguard to tie in this concept for my DeAr22! I know no links will be shared but if you happen to have some good sources for scales and other blender packs please drop me a link! Also thoughts and constructive criticism is always welcome! Like if this is rage bait for some please say it! Why do you hate it, what would you change! This helps in my noob creative process! Yes this will have an FTN with about 1/4th of it coming out of the mouth!
