You have some wonderful color of warm yellows and oranges in this composition. However there are a few areas that need improvement to improve visual appeal. I know Mother Nature is difficult to work with - she never seems to co-operate when you want the shot to be just so:-) I think that the composition showing the full brightness of the globed sun simply does not complement the shot. That strong orb of light washes out many of the details in the surface of the ocean and the bottom half of the sailboat if it is not exposed correctly. Not to mention it really dominates the scene because our eye is immediately drawn too it and then we look away because of it's brightness. Hmmm, perhaps closing down the aperture to an 8 or higher would get some glints off the ocean surface (for here it looks a flat orange with no surface texture to speak of) and the silhouette of the boat on the surface mayhap might be stronger with more definition to make out the details of the whole boat (I can only see the sails clearly). If closing down the aperture doesn't work effectively I think it might have been better timing to take the shot with the sun behind the cloud or just barely peeping out. You might get lucky and have some beams of light shooting forth out of the cloud work thereby making the composition even more visually interesting.
Very vivid colors. I does seem a bit oversharp but that could be partly the high contrast evident in these conditions. I like the competion of triangles with round sun.
nice try, but i think the sun behind the clouds in the original gives the apearance of god being with the sailboat, whereas yours is a boat, all alone.
