The move 20. ... a5 was bad because b6 pawn is unguarded and vulnerable. I also missed the line 21. Rg6 and overlooked f7 pawn pin.
21. Rg6 a4
The move 21. ... a4 is a serious blunder. The continuation 21. ... Ra6 22. Bc4 b5 might save black position i guess.
22. Rxb6 axb3 23. Rxb7 bxc2 24. Kxc2 Ra-c8+ 
Now the a and b pawn can easily nail the coffin for black :(

The King is out of play and Rook can grab the black pawns easily.
Note: These are my thoughts on the position during my play. Any comments and analysis are welcome.
