Japan: Hiroshima - Sushi rolling

Finally tried my hand at sushi rolling, only to find out I STINK! I took a Japanese cooking class where we made California rolls. It was delicious, but you have to make the sushi rice just right - the amount of rice vinegar that is mixed into the rice is definitely what gives it the best taste. I've had sushi where they don't put rice vinegar in and it is too plain and blah without.

Here are pics of my attempts. Notice the insides were squished out of my first roll, otherwise I made them too fat.
