Love the reflections :) Always a great subject for a contest! I've actually recently started one of my own - @weddingcontest specifically to curate a wedding and portraits community here on Steemit.
As you said, the key to contests is finding the ones that fit your skillset. Weddings is a lot more niche on here at the minute but as the community grows I'm hoping we'll see growth within the weddings community :)
Anyway I always enjoy your posts on photography, I write lots of articles on here myself and just wanted to share the wedding contest idea with you :) Any support would be greatly appreciated but I totally realise it's not really your area of interest!
