Critique this?

EXIF:

Very cool photo with interesting subject matter, for sure. The only critique I have is that the image looks like it might be alittle under exposed, what does your histogram look like.

Thanks!

I really think this is a sensational image! I love the dramatic colours and contrasts - the jellyfish look great! Frankly I'm really hard pressed to find anything remotely negative about it!

I would like to know a bit more about this image. Where did you take it and what kind of post work did you do to it?

Thanks! I took this at the Aquarium of the Pacific in Long Beach, California. Was using my 50mm at the time and it was really dark in the room so in CS5 I believe i bumped up the exposure just a tad, sharpened a tad and used vibrance just a tad. lol
