Hello, TKNY
I think that your work has great potential. You are doing a great job with your skin tones. The shading is good as are the highlights.
What I am having a problem with is the cloth. It looks like there is not enough definition because I cannot really make out what it is. I know it is a cloth but it looks too chaotic. Try to work on better defining the highlights and shadows. If it helps when you lay down your basecoat try shading with some thinned down paint to help define the shadows that way you know where to add more shadows and it will also help see where highlights go.
But not a bad work. Rackham minis are not easy to paint.
