Telestu,
I think Silman would say that you're position is dynamically imbalanced, nearly equal, with a slight edge for Black.
a ) Queens are equal
b) Black's Rook controls an open file, White Rook on a semi-open file.
c) Bishops are nearly equal but Black's light squared one (although useful) looks like a giant pawn with semi-Bishop powers at the moment
d) Black's N is well posted while White's N potentially could be.
e) White's b2 pawn is separated from the a pawn.. other pawns being equal
f) White has space advantage on Queenside, Black Kingside
Rely more on yourself and less on external factors to decide what to do, you'll play better such positions, but also stop playing chess.
