I agree that it's too sharpened. And if I didn't know it was Anfield Road, i wouldn't have recognized it, because it's so dark. But i still like it though.
If i was making a stadium wallpaper, i would make on huge pic from the same angle as yours, but then I'd add 1 or 2 smaller pics of the stadium from different angles. Fx. from up in the air, and ome from the outside. That would give a very good effect, if you could find a good spot and a good way to add them.
Keep it coming mate.
