Yes. Yes. ANOTHER version of these. The changes are, with some exceptions, quite subtle and are mostly animation changes I figured out while working on the "emoting" animations. One big change is reshading the "back" sprites so they are less flat looking. Another is that I made the "left-facing" views properly different from the "right-facing ones", which were mostly just flipped horizontal. I also had to change a lot of arm and leg positions, in general, because they were incorrect. I also softened the internal outlines where possible, warming up the overall colors and shading a little.
I keep fine-tuning them as I develop other art. I think this is a kind of trap indie devs probably get into all the time. I think v5 might be the last, though. Might be!
