Since Esteemed is still kind of "in beta" so to speak (the full story proper hasn't started yet), more dedicated folks wanting to follow every update will want to follow the series' Facebook page, which even now, has a few pieces of art (and Tumblr links to the original artist posts) that aren't ready for DA primetime yet. You can find that group here: [link]
In meantime, more Esteemed artworks will continue to be made, as I'm commissioning various scenes I have planned to be drawn out -- so by the time the story starts there will already be plenty of artwork for reference. If you're bored and enjoyed the initial excerpt, you could try out my more amateur Toph story, Worst Field Trip Ever ([link]), or give my primary project, What I Learned at SRU ([link]), a try, as the latter boasts a fiction/fanart combo similar to what I have in mind for this project. Esteemed will become my main focus once SRU is finished.
Otherwise, please check out the galleries of art, feel free to submit your own, or check out any of the Affiliate Groups below to explore what this fandom has to offer!
Thanks for everyone's support!
