First 1500 win

Milestone. First time defeating a 1500 opponent with slow time controls. I was playing White. He neglected development and wasted tempi with a6 and h6. I believe this is also my shortest game to date. Opponent's rating: 1514.

1. e4 e5
2. Nf3 Nc6
3. d4 exd4
4. Nxd4 h6
{h6 seems too passive. Want to develop KB. Considered Bb5, Bc4 and Be2. Chose Bc4 for activity.}
5. Bc4 Qf6
{Q takes the N's best square and forces it to e7 later in the game.}
6. Be3 (6. Nb5 Bb4+ 7. N1c3)
6... a6
{Again, very passive and ignoring development. Considered Nc3 and 0-0.}
7. O-O Ne5
{Need to move the B. Considered Be2 but didn't like the fact that e-file is crowded. I want to keep e and f open for the pawn advance. Fritz recommends Be2.}
8. Bb3 c5
{I notice that the B is trapped. However, Black will have to use at least 1 tempo to capture and he is way behind in development. I see Nc3 will threaten c7 by way of d5. I considered Nc3 but decided to save the N by moving into enemy territory. Fritz recommends using this opportunity to attack with f4.}
9. Nf5 c4
{Considered f4 and Nc3.}
10. f4 cxb3
{Here I need to continue the previous idea with fxe5. I mistakenly thought that opening up files would aid my attack on the uncastled King.}
11. axb3
{Oppening the a-file for my R. B's K will be stuck in the middle for at least three more moves. I plan on putting on the pressure with my sup development. Fritz considers this a bad move.} (11. fxe5 bxc2 12. Qxc2 Qxe5)
11...Nc6
12. Nc3 Nge7
13. Nd6+ {Black resigns} 1-0
