Hi Reggie, and welcome to WW.
Your play sounds very interesting and I wish you lots of luck with it. If you would like offer it for critique, it is best to post in a group, because that is where critiquing takes place on the site. Join a group that is active and seems suitable for your work and post it there. At 18k words your work is rather long to post in one piece, and initially it would be better to post the first thousand words or so. The groups are based on reciprocation, and so to ensure you receive critiques, it is important to give critiques of other writers work. This pleasing harmony of give and receive will encourage others to comment on your play.
