[Concept Art] Spine yet again

Some more experiments for my (maybe) next story. Many of these designs are probably going to change again heavily. I'm still struggling to emotionally connect with half of the cast. For this story for the first time I tried a more analytical approach instead of intuitive writing, like.. following actual writing guidelines and rules and charts and giving each character goals, obstacles and flaws - but I think that approach is just not for me. It doesn't matter if the writing "works" from a technical perspective - if I'm not feeling it, I won't enjoy making it, and then I won't make it, because what's the point really if you're not having fun? Also, I want to include so many things but I also want it to be short LOL. I'm hoping once I figure out the main point to get attached to, everything else will fall into place. With TBH it was so easy.
