The details are wonderful. The composition is good. The rope idea is creative but it doesn't say wedding to me. Maybe if you would have had a pretty rope (not an old worn out one) tied in a knot with the bride and groom holding the ends. Not like tug of war or anything. Gently holding the rope together showing the wedding bands on the fingers. I think that if it was more "wedding" looking it would have done better.
Good luck in future challenges.
Interesting photo but...... I'm not normally a stickler for titles but IMO this challenge had very defined rules about the title and you seem to have ignored them. "Weddings" may have been a better title, keeping within the rules.
Clever and I can see this as a card. I think the title is too long but I'm just one who hates long titles. I think "Tying the Knot" would have sufficed. Good lighting and the hairy detail of the rope is great. Not overly interesting, but it certainly works for the category.
