A good view of the city, especially at sunset, , can be seen down Arden Road, Alum Rock. Well it was in the ' 80's when I got off the number 8 bus to go home.
As has already been mentioned! on this thread, the view across Bartley Green Reservoir is fantastic. My camera isn't good enough to take a decent picture, but if you you Google Images there are some lovely photos there. Brum looks a real world city.
Further afield, I went up the tower in the church in Warwick, a great view of the Birmingham skyline could be viewed.
