This is the YG-4210. I'm not too happy with the cockpit, but I like it otherwise. I wasn't going for the "studless" look because I'm not that good. However, I think the studs give the ship a more rugged look, which helps in this case. the ship has one cockpit, two cargo holds, and two crew quarters. This was made using Lego Digital Designer. Below is a link to the LDD gallery where you can download the creation.
