Now that you're asking ... yes, they might be a tad distracting. But I feel I can say only little at 500x333px ... it is very SMALL. The clouds, however, look GOOD from what I can see now.
Better ... might be way large for some, but just fits my screen in one go.
Now I wonder: is this a black and white negative photo, or one taken in black and white mode but digitally, or is it a conversion? If it is the latter, how did you go about converting?
It seems a bit grey all in all, I feel that the subject as much might merit some stronger contrasts. Some real black and SOME real white, where it is to be had.
Try to convert your colour photos via the Channel Mixer - it is more fun and the outcome can be so much more varied. Channel Mixer, tick to "Grayscale", and then shift the levers and look what you get.
