I've seen a couple of variations of this happening as well, but my eye landed on a post by Thomas Scholes where he was talking about concepting up a quick prop every day in October. Deciding it was a great idea to get some concept practice in I took up a Proptober quest of my own. Today's was done super fast before bed last night. Tonight I'd like to give myself enough to time to get a little more "painterly" with the rendering rather than just uncleaned up line and wash. Still a lot of fun though, and I'm looking forward to trying out some different styles of linework/rendering as well. Anyway here it is Proptober Prop 1, "Preserved Astral Polyp"
"Shamans of the Danar region are renown for their ability to pluck these psychic parasites off dimensional travelers and bottle them in jars made of a mysterious glass."
