I do like the logo but I think you might have taken it too literal. Maybe if you just toned down the waves and made them a little simpler it might be better.
I usually like your logo concepts but I just am not digging this one. It really doesn't feel like a logo, more like a postcard or mailer of some sort. It's also a pretty complicated logo that I think you may run into some printing problems. I would say take another stab at this.
As Christopher said, you might have taken it too literally.
You may also try to show the tides by breaking the text and drawing within the shape of the font.
The waves just don't work for me. Like Nate i normally like your logo designs, but this is very dated looking for my liking.
You could maybe try the waves going through the text, rather than what you have now. Just an idea though.
From past works you have put on here, I would almost say that you may have suffered from some sort of head trauma!
The font is old and boring and the waves are just dull and lifeless, seems odd that they are cut off on the sides...
Back to the drawing board with it!
Good Luck!
This seems more like a banner than a stand alone logo. Especially with the sides vertically cut off. I think you need to make it more self-containing if that makes sense.
I don't think it works very well. It all looks a bit confused and out of order. I get what your trying to do but you need to spend more time illustrating the water.
I had an idea about your logo, tides are caused by the moon moving around the planet and pulling the water around. So you could take it quite literally and have two different sized spheres representing the earth and the moon, with the water on earth somehow being pulled towards the moon, which could look like cogs or something relevant to the other words.
Don't know if that helps, or if I just sound like I have had a few too many ales.
Simplify is all I can say... or redo. Perhaps a different take on waves with a different font for "Tides" would work without the complicated gradients.
