Seems like you're further expanding upon the style without outlines, but going even further with regard to the forms; not keeping them as solid, but swift and airy where possible, yet still with a neater form of shading/light than most. I really like the style, and the princess in particular (if that's what she is?) seems really detailed, though wonder if some textures could come across better with a different color, or shading, or maybe gradients too. The metal, and parts of the wolf-creature shields in particular. It seems a bit bland the way it doesn't reflect light. The one with a shadow has his shadow falling the wrong way too, more toward the light than away from it... but overall really smooth work on the details! I like the angle too, with the symmetrical walls going off into the distance, and two towers on each side. Gives it a pretty cool game-like vibe, and really lends focus to what's going on in the middle.
