Did I play this too aggressively?

[CasaJJ]

I didn't have any read on villain as we had only been sitting at the table together for a short time. In the first two orbits at the table I was on a sick run, getting amazing cards and betting very aggressively. That being said, I only had to show down a couple of times. Because of that I'm sure that villain thought I was an absolute maniac when this hand came up in my third orbit.

Did I play it too aggressively? With a double gutshot straight, a flush draw and two overs plus my maniac image I thought it best to bet hard. Should I have slowed down?
