Sci-fi Laser Rifle

i made this laser rifle mainly just to practice texturing. the model it self is only 17000 triangles but i put lots of effort into the textures just as practice. i tried making the sight using mesh instead of flat plains which worked well. i just kinda wish i was better at rendering as my renders look kind of boring. i did use someone's concept art for this and i really wish i could credit them but i can not find the original artist at all as i got their work from a whacky google search.
