Retrofuturistic rifle concept image - PLing

I'm a 20-year old 2D/3D artist currently studying Game Design at Adulta Oy, Helsinki. Some day, when I grow up, I want to be a real concept artist or character modeler. I've got over 5 years of experience in 3dsMax and Photoshop and concentrate largely on low-poly game models and weapon/character conceptualization. I can also use Maya, zBrush and Mudbox if needed be and I'm currently working on some concept art.
