Hey, thanks for this neat summary, I didn´t know about some of these contests :) Let me add mine.
I run a weekly Steem price tipping challenge (last round can be found here), a weekly upvote giveaway (not really a contest but it´s finally getting some traction, last round is here) and I also organize random photo contests on various themes :)
Sorry I missed your contest, now added. Let me know when you next do a photo contest.
Thanks :) Will do.
