Here is a fantastic page of Dree Elle development artwork by storyboard artist Steve Hickner. This page accompanied the storyboards for the season one He-Man episode "Dawn of Dragoon". As the character model had yet to be designed, Steve illustrated his idea of what Dree Elle should look like. While I prefer the final model, I do like the direction that Steve was going with the character.
