I much prefer your more subtle indication of the abbreviation S.E.A. You made the right choice leaving off Inc. too.
I am not sure the splash coming off the S is working. I have always wondered if someone could suggest a wave with the S somehow.
The letters are very clean and strong. There are two directions I could see going. One is to thinner, more elegant letters. The second is to make the letters like a big window on the sea which is very nicely suggested by your coloring, and suggest the letters only with negative white space. I can imagine seeing a fish or two swimming above in the lighter blue space.
