Sci Fi Gun Practice

Short project where i wanted to brush up on my Hi/Low bakes and PBR texturing. And go 1:1 with concept. Gun has 10k polygons. I found this concept image somewhere online and only now, when i was about to upload i decided to image search on google for the author and i see its an Artstation Artist (of course). I hope he wont mind i borrowed his awesome concept :)
