Need input on next commission opening! (Patreon)

Hi everyone! I currently have one and a half commission requests to do but I would like to open a batch of commissions before the year ends... and would like to do that soon.... ;o

This opening would have like 5 slots, and you MUST have all the required details ready for me. Now, a question to ask you all: should I announce the opening with a reminder on a specific day? a specific day AND time? or entirely random with no reminder?
