If you want an honest awnser, i dont think its good, with some singing lessons you can get yourself a pretty decent voice i reckon, but it just isnt good now.. Do someting like this: link
And what i mean with that is. I'm not a great singer either, but i'm singing for something over 3 years now, and i 'm still trying to find songs that fit my voice (that showcase me as an allright singer) And it might not be a Queen song (My link shows a U2 Cover) but after a while you can develop a better technique and can try to sing Queen songs wich arent that hard to sing (Days Of Our Lives for instance is alright, Radio Gaga, We Will Rock You..)
I think as others have said that you need practice. I've just sorta picked up the singing bug about three years ago myself, and while I still sound like a whale farting under water I can tell its much better than what I sounded like three years ago.
Here is one of my attempts at sounding like Big E. link

If you sing great in your opinion, you're pretty much well... deaf :D
Nah, thats a bit harsh. But i mean, its your opinion.
I think that i can sing with a good tone sometimes, but other people have different oppinions about it...
