Oh shame on me for not linking astrofaces. Sometimes it's eery! Great resource. If it's turning astro into a parlor game, so be it! It's uber fun, and great for developing both intuitive and observation skills.
Ok, yes I am totally vibing some Leo up in there. It may be placed in a way that doesnt turn your chart off like normally. Of course you can't apply this all the time, but often times blonde hair and blue eyes make me think of Air or Water signs, OR Leo. Like the guy who played Thor. The detail about the yellow bracelet even makes me think Leo perhaps. Like it's a little sporty- is he athletic? If a regular athlete, that helps the Leo case. Oh, also the tattoo.
Yeah, I'm with you, he sounds like Earth/Fire. If he is Fire dominant, he will be more smiley and excitable. It's harder to tell without being around him in person. The not seeming impulsive takes away the fire like you said. If I had to guess, I'd say like Taurus with Leo rising. Or a Leo moon (wants to be noticed?).
One of my favorite ways to get a better idea of what he may be is to think of what celeb he looks like/reminds you of. I've found this to be a pretty accurate approach.
This is one of my favorite topics ever~ and you sound a bit like me; therefore, I'm going to also recommend the astro blog:
http://www.MysticMedusa.com. She's educational, accurate, trendy, and hilarious. She's an Australian Pisces Sun with Leo Rising and Libra Moon, which sums those adjectives in a lot of ways lol. It's like reading a fab indie magazine woven by astro knowledge.
*PS: I was totally picking up some Gemini in my earlier post btw, so I guess that was you! lol
