Hello. The logo now ranked #1 (#21) is closest to the ideal.
Just a couple of further refinements, and I think we're finished. Please refer to the original drawings we submitted to relate to the following information:
A) The wave should have a cresting 'peak', as shown in the black and white drawing, but it should be much smaller, cresting just below the lighthouse window, but a definite peak rather than the rolling waves you show.
In your drawing #5, #6, and #7, you show a peak of the wave at the left of the drawing; simply move that wave peak to just below the lighthouse window.
B) We like the shape of the lighthouse top in the colored drawing, rather than the one in your rendering. Please use that shape and modify as you think necessary.
Again, great job!
