I really like the concept of this piece and I can tell you definitely put a lot of effort into it. I tried to do some overpainting. Just some stuff I did and suggest: - Increased overall saturation of the painting because it looked a bit washed out to me. - Tried to adjust the anatomy but I recommend playing around with a 3D model as reference for the pose and experiment with some camera angles and lens settings, since this is a very challenging perspective. - Reduced the intensity of the lighting on her face and increased the brightness of the blue light under her instead. - Gave it a bit of a vignette effect so the focus would be more on her, also darken her braids to push it back into the background more. - Added a layer of purple tint over her so the colours feels more cohesive. - The angle of the tiles are off for this perspective but you can fix that easily if you also use a 3D model reference for this specific angle and perspective. Overall this is a very ambitious piece so lots of references will definitely be beneficial.
