I have to disagree with those that say aroma doesn't contribute to flavor. Flavor is made up of two parts: Taste and Aroma. Taste is what our tongues detect, and consist of five senses: sweet, sour, salt, bitter, and umami (savory). Aroma is what olfactory nerves in your nose and throat detect. The brain interprets these two sensations together as Flavor. So, when something adds Aroma (which many think of only as smell) it does add Flavor as well. Which is why we're told as children to hold our nose when eating/drinking something that tastes bad. This doesn't completely work because there are olfactory nerves in the throat that allow us to still detect the aroma aspect of flavor.
In this case, you will have a beer that is heavy on the bitter aspect of flavor, but lacking on the aroma, which is not only smell. What the others have said is that two beers will taste exactly the same if one is dry hopped, and the other isn't (all other things being equal.) They are also saying that there is no point in dry hopping a beer with high IBUs, since all you would be effecting is the smell of the beer. But, again, IBUs only determine bitterness, not the entire flavor of the beer.
That being said, you probably still have a decent beer. I wouldn't go entering it in any competitions unless you had a bunch of late-addition hops, but it should still be good.
