Mahalo Nui Loa

I think the illustration needs improvement. The water looks dirty and hard to make out what the guy is doing. I guess surfing, but hard to tell.

The Nui loa is making the overall logo messy as it overlaps too many elements. Try to find a better position for it.

A lot of nice elements at play here but they don't seem to be getting along very well.

It's super busy for a logo and I agree with botw, I have no idea what that person is doing there. I didn't even think it was water.

Try to condense it, maybe? Bring those palm trees into the circle somehow and maybe lose that figure entirely. What's the message or emotion you're trying to convey? Make that the focus.

Try to simplify all the elements of the logo, it could be difficult to print it and read it if you reduce it.

I agree, the logo was too complex,, may be more simple.
This logo can be seen clearly if the size is big but not to small.

Great, but too complex. You may try putting just one palm tree, simplify the image in the circle, work harder choosing colors (Adobe Kuler is a good instrument to help you choosing them).
