This sketch was completed a number of months ago actually, been on the back burner because I was both inking it traditionally and trying to digitally render it without the sketch for use as reference pics for each of these characters going forward. However, as inactivity on a piece often does, that effort was abandoned due to not being actively pursued for too long. Plus, I have new ideas for their reference sheets.
These are the current working concepts respectively for Jean (previously 'Jon'), Sev, Devon, and Tina. All of them have appeared in my gallery before, some vastly more different than others. Note the "1" in the title however as this is just a portion of the planned main cast, I hope to follow up with more in the near future so I can FINALLY have a visual representation of them all.
I normally hate slapping huge watermarks on images or letting dA do it for me as I am with this, but consider it a WIP. I may return and color these after all so then that'll be gone.
