At 4 months of age, you really cannot judge a dry mead. Give it another year and you'll be able to see what it turns into. The aroma usually develops quite a bit over that time and the body may develop as well.
If it is a low ABV mead, however, it may remain thin. What was the starting gravity, the final gravity, the yeast, etc.?
It may need some acidity to brighten the flavor so it doesn't taste flat (depending on the honey), but you have something with 14% ABV so it should develop body and aroma and flavor with age. The honey aroma comes back with dry meads after several months. You can check the acid by taking a glass and adding a few drops of lemon juice (or a tiny bit of acid blend) to see if that perks up the flavor.
I don't like to make traditional dry meads at 14% ABV because I find the alcohol is too "hot" for my tastes in most cases (giving the Sake sensation), but it normally mellows with age as the alcohol integrates. I think this mead may yet earn your favor, but it will need another year to get there. I'd store it away someplace and taste it again at Christmas.
