Logo Design - Donegal Kitesurf School

So I have been sent a request to create a logo, the rough idea had already been doodled down so this project is more how to turn a doodle into a completed logo rather than any initial conception of ideas.
I was sent this sketch and so based all my work on the notes it gives.

I had a look at the mountains first and looked around online to get a good idea.

This is the coors light mountains he was thinking about.

Using this I created the first idea taking a section of the mountains and drawing a path around on Illustrator.

Although I quite liked these I felt it wasn't quite right so created the mountains myself.

I also added the sea and the kitesurfer as the sketch and notes requested to make these 4 variations.

These were almost completely created using Illustrator (CS4) from paths and solid fill or gradients, there was a little photoshopping at the end to finish this off.

The bottom right is nearest to the design requested however I quite like the design with half or no circle around it.
