As I mentioned previously, at the very beginning I chose Caves as one of the places where slime molds can be found. And what this gave me was a further research about this environment and , most importantly, the lighting. See-through slime molds in dark caves are lighten by glow worms, their neighbors.
So this is First 3 concept drawing of what I imagine the Animation is going to look like. Maybe it’s going to be less textured (if it's going to destract from the slime mold transformation), so far what I notice. I'll see.
