I've been going around as a writer, but started getting drawn into Concept Art and 3D modeling. I'm currently finishing my studies as a 3D artist and will then be let loose on the world. Beware!
Got around making a scope and such stuff. Worked a bit more on the body and carved out the bits where I had placeholders. I didn't think it would take so long, but now I have most of the parts to begin sculpting. I also worked on an ejection port, but it is not presentable yet; have some ideas about what to change.
Your input was great, thanks a lot! I hope I can end the modeling soon and get to texturing, which will be pretty challenging with this clean kind of weapon. It's easier to texture completely beat up stuff.
