First time rolling. Thoughts?

This was my first time rolling sushi. I bought some sushi grade tuna. Filled with tuna, cucumber, panko, wasabi, and spicy mayo (mayo, Sriracha, sesame oil). I tried half with the nori on the outside, and the other half with rice on the outside! Tasted pretty good. The ones with the rice on the outside were a little harder to get a tight roll on.
