Neptune's Obelisk

Hello there :3 It's lovely to see Scylla's serpent form again~

I feel like I keep saying this a lot, but I like the colours in this picture. Truth be told, I generally like your sense of colouring. As with the monochrome picture, you seem to have a strong sense of how colours function, but here it is built upon in the way that there are multiple colours and each have their distinct hues depending on the surface material, lights and other qualities. The general lighting has a very outdoor-y feel to it and especially Scylla's hide has a lovely glistening quality to it, as such hide would have, were it real.
The colours and specifically the textures here work really well, items like Scylla's hide and the grass in the background not only has appropriate colouring (and even ties in with the general lighting of a cloudy day) but more importantly holds texture qualities that differentiate the source material. The grass has clearer shadows as individual blades of grass form shapes according to how the wind moves them about, while Scylla's hide has a more gradual shading since it is being lighted from a very wide angle and is surrounded by a material that strongly reflects light. Speaking of the sea, I like how you've improved the colouring, this time around the sea has clear shapes but is still quite softly coloured, making it seem very fluid. The highlights work wonders towards the general feeling of how the water behaves and acts, and I just LOVE the fact that you included a shadow cast by Scylla on the water's surface. It solidifies the feeling that the water in the picture is a large enough "pool" to not only reflect light on a general level but also deep enough to be able to be cast a shadow upon.
What I feel is also notheworthy is how you've built upon Scylla's skull structure and seemingly focused it a lot from previous pictures. She has a lot more detailed and strictly formed structure in her head this time around, which leads itself to the strengthened feeling of depth and 3D-space than before, I feel. The shadows on her also work towards that goal, but I think the greatest change is how much her skull structure shows through her head. I mean, the skull has been structured and designed so well that the facial muscles and other details just seem to fall into place like they naturally belong there, and personally I see that as a very impressive feat, especially considering that I'm practicing on that myself and it is no easy feat to accomplish ._. You've done really well!
All in all I like what is happening to your style and how you've carried your sense of colouring along with your ever-improving anatomical and perceptional skills! :3
