6 max NL25 KKK getting action

[Yorkshire Pud]

No reads on Villain, only got 12 hands on him.

I'm pretty happy with my play here with the exception of my turn raise which I think is excessive and cahses all but other monsters out.Idon't know why I chose to raise this much,maybe not paying attention as I was multitabling? What would a more reasonable raise be here, around $5-7??
