Merman

I've had a re-occuring dream over the last few days involving a reserach station in the middle of the ocean and merfolk.  Its snatches and I cant seem to hear the story... am hoping by sketching them it will come clearer.

Todays picture is of one of the mermen - pressed up against the large glass observatory windows overlooking the depths within the station.

My lack of knowledge of male anatomy requires me to go and perve at men in gyms... purly for artisitc purposes - obvioulsy.... any takers?
