I'm (was) a fourth year.
Yeah, I don't know what kind of advice to give you. I guess just work on lifedrawing like your life depended on it and work your ass off. Just remember most likely that nothing you do in first, second or third year will make it into your final portfolio, so those years are a great chance to just go nuts and experiment as much as possible.
Best of luck to you! Looking at your stuff I'm sure you'll do fine.
