Homemade Sushi Plates

I had a craving for sushi so I raided my freezer today to put together two sushi plates.  The triangle tamagoryaki pieces were my first attempt at making it.  The tamagoryaki whole roll was my second attempt.  How does everything look?  Any advice to improve? 

I’ve been working on my fish filleting skills for the past few months.  The yellow tail (top), sea bass) left and chinook salmon  all came  from Costco as whole fish.  The tuna was part of a block I bought  from a local fish supply store. I made Saku blocks out of it.
