Wow, very nice!!!

I think you could crop some of all the dead space from the top for a more dynamic image, but good effect, none the less!

Just a tad more light on that stovepipe hat will make up the difference in what looks like waaaaaaaaaay too much dead space on top.

Agree with Elemare. This could be a much more powerful image.
EDIT: Now it's overkill.

Thanks to all for your usefull advices

agree with the others

The lensflare is distracting. It became the focal point.

i like it...

I've followed your good advice MossyB, hope it's better now !

Better to have "dead space" at the top, rather than a "stab your eye" bright spot commanding you to focus on it...
