There are lots of effects about - particularly apps that turn photos into paintings, adding textures, frames etc. Most of these are good fun and some have been used very effectively. The find edges filter is probably used in a number of these apps e.g. Watercolour simulation. In this case, used on its own, i am not sure it adds anything to the subject - I don't get winter arrived from the effect - the original would probably portray it better (if it could be seen). The assessment of an effect is whether it enhances the subject rather than being the subject -imo

As already mentioned it is a good image with strong interest and colours - well processed. Whilst I understand your title and therefore the desire to include the closest rock, I feel it unbalances the composition. A crop above this rock resolves this and places the second rock in a balanced position with the setting sun. Also, but arguably, it places the wave band in a better position in the composition.

As the image stands there is a temptation to see the image in two halves, the sun and the light reflected on the sea and the two rocks. There is a case to crop out the rocks altogether and focus solely on the first half - making the light the subject of the composition.

It would be interested to know whether it would have be possible to create an angle between the rocks and the setting sun at the taking stage by moving to the right. Also would it have possible to have taken the image without a wave band and would this improve the image - sometimes strong horizontals segment compositions particularly when they run through the middle.

Thanks Barry, Ken, for the comments.

Thanks Terry - I was not totally convinced by this image. It has the drama but the colours and the brightness around the lighthouse jar a little for my taste - that said I find my own images hard to pick at times and despite the general lower volumes of votes and comments on the site it is still a good place to get feedback.

Thanks all - great to have some comments It wasn't really possible to keep me out of the pictures so I decided to join the selfie age

A square crop provides a destination for the walker and emphasises the light, the hills behind, and brings the birds in the air and the surfer into the composition. Whether a crop changes the mood or not is interesting - may be he does not look so lonely in a square - perhaps it is now purposeful or thoughtful?

Wonderful capture
