How do you like these bluffs? 5/10nl

[jaywks]

Here are two bluffs that I pulled. Given my line and villain's line in both hands, are these good spots for a bluff? Basically, am I repping a reasonable hand, and do you think that it'll work.

In the first hand villain is 22/15/2 over 529 hands.

In the second hand villain is 27/16/2 over 143 hands.

No real reads other than those statistics. I don't know their playing styles if they're a calling station and no real history.
