I saw your timelapse videos.
Continue posting your old art till 21 days of your previous Whale curation.(That is the cooldown period where you cant be curated as you been curied with whale votes)

Make sure the 1st post after these 21 days is a your best fresh art(as in both the art and youtube timelapse video should be a new upload i.e it should not be uploaded)
This should make your case strong for your second whale curation.
