NL50 AQo TPTK mono flop, turn decision

[ninjadanger]

villain is new to the table, no stats, no reads.

raise on the flop seems standard, maybe a little on the small side. I was hoping to get to a free river where I could call if he leads for a reasonable amount or vbet if he checks. this is a fold on the turn right? villain has ~25 total going into the turn.
