As miffed said i think you could extact more with this image. 25$ on turn and all in river is what i would do if you truly had a fish maniac image(especially if this guy is not very good).

I mean pot is 22$ on turn, you could bet more than 15$. And on river again i think he calls more. Maybe my betting ammounts are excessive but you can surely get more than this.

Nice hand sir
