Your website is good - simple, easy to navigate and browse your work. You should make your contact information more apparent on the front page, and put a small link to your resume up top somewhere. Right now it is located awkwardly on the bottom under all the art and is easy to miss.
Your work - you have a weapon/prop, environment, creature, and character bust. The sniper rifle is a bit too whimsical for my tastes but all of your work is solid considering your experience level. These days, however, many employers want specialization. Until you become more senior in this industry you should probably focus your portfolio on a single facet such as environments, or weapon/props, or characters, etc.
