I already like this position - both my bishops have open diagonals and I’m basically one move away from castling.

I think white is making too many pawn moves.

Because white is not close to being able to castle, this move seemed very natural

The dark-squared bishop is much better positioned on d6, even without the threatened capture by white’s queen’s rook

White’s pieces seem so bunched together and cramped around the king that I immediately thought of sacrificing my rook to keep the white king in the middle of the board

I couldn’t resist this sacrifice, though it by no means led to a clear win (as far as I could see.)

Logical follow up to the rook sacrifice

Eyeing white’s f2 square which is very weak and difficult to protect

I expected this and thought it was white’s only move

Centralizing my rook because I figured my light-squared bishop was immune from capture
