Very well done. Very nice to see someone be as creative as you were. I like that you actually thought this shot out and put some effort into it, it shows. The shot is well done. Composition is okay I would have cropped a bit tighter but no big deal there. The lighting seems a bit bright...flash I suspect. Side or back lighting would have been much better. Sharpness and focus are very nice as is DOF. This would be a great shot to play with in Post Processing. So many thing you could do here. Enjoy and congrats on a great shot.
Some great textures here nicely caught in the light with the rest of the scene fading into the blackness - that works well. I find this strengthened (for me) by a tighter crop, particularly at top and left but also at bottom.
Different and unexpected. I like it. The linear aspect along with the curvature of the horseshoes is a nice effect. This would be great with a sepia and grain too - even make it look more nostalgic.
