[100NL] Is this spew? Repping AK

[kenadams]

I don't know how villain got his stack. He was 55/0/1.5 over ~100 hands. I hoped to take it down preflop obviously. I wasn't sure if I should c-bet or not, but in the end decided to do it (how's the size?). Once he calls I put him on a pocket pair of some sort; Normally I would be done with the hand at this point, but I thought the K was a great card for me as it allowed me to rep AK, so I pushed for a PSB.
Spew?
Comments on all streets appreciated.
