Wheat beers can be more dry than barley malt beers...what % wheat did you use?
It's probably a little more tart because of the acid in the strawberry coming out as the yeast consumed all the sugar. Wort is always sweet so I'm not surprised by that.
Nottingham isn't a particularly dry-finishing yeast, so it should leave a little bit of maltiness or sweetness.
As The Pol said, you can't tell a *lot* yet. Give it a few weeks. The strawberry mead we made wasn't any good until it hit 18 months old...your beer shouldn't take that long, hopefully.

Yes, that *is* beer. Water, malt, hops, and yeast mean it's beer. Go ahead and try a glass...
