I think the 2nd is the best to paint. The first has too much silhouette stuff going on (which I like to paint actually) and the figures are big enough to be interesting but not so big that it takes 3 months to paint them. It'd also be interesting to see how people deal with the jetty.

The 3rd one is simply a great photo, but I think the woman is too prominent in the picture and would require work of a level that is beyond all but one of us (yes, Nige, you).
