I tried watching a bit of Death Note. I really should finished it soon. I haven't heard of Trigun, but I'll definitely look into it now
Fullmetal Alchemist is really good. They started a new season a few months ago that is based on the manga, and it's getting quite exciting. The first season was really good too, though, so I suggest you start with that one.
The person in my avatar is Ryan Ross the (former) guitarist and lyricist of Panic at the Disco. He just recently dropped out of the band with the bassist, but he's still a good musician, and I really like the picture.
