Ground/Dragon, because dragons and it looks like there's a lot of sand and dirt in your avatar and signature.
Dragon, Dark because it feels that way to me because your avatar and how your name is spelled for same reason makes me think of demon dragons I made in my head not evil but not completely good either and they rile in the darkness (the youngest one mostly)
This almost makes me want to change my username. Anyway, the sad Umbreon is a Dark-Water type because symbolism.
Just for the fun of it, let's say that you're a ice/fighting type, and the 'fire' part of your name is a misnomer.
