Well, all the folks above gave you excellent advice, following that you should get better votes.
I think, though, that this mini is already a 6. I mean, that is only 1 point above \"tabletop\" quality...It is definately that.
Your realistic style may hurt as well. Not that there is anything wrong with it at all (I quite like it) but I think voters tend to vote higher for things that are more exaggerated. Many arguments evolve around this. Some historical or military modellers tend to use less highlights and go for the realistic \'in scale\' painting. For instance, many believe that the miniature should be painted as it were a real person, being viewed from 100 yards away (or something like that). So small details, and even bright colors all get taken out.
I am not saying this is what you are doing, but rather this is what it kind of reminds me of. I believe to get your scores higher, you have to force highlights, and really make details overly dramatic.
Of course, that is just my opinion, so take it for what it\'s worth (my opinion plus .85 cents will get you a cup of coffee!)lollol
