It's a solid tabletop figure - nothing to be ashamed of. Personslly, I do my basecoating and highlighting (or vice versa) and then work in shading - I think sort of thing might've worked better here on the flesh areas so as to avoid the harsher transitions in from the edges up to the highlights, but whatever. Everybody paints with a different approach.
I can't really add much to what was said, other than thinning your paints is a necessity. Maybe not so much for basecoats (like 1:1) but for highlights and details and such, it's a necessity! (Just make sure you wick off the excess liquid on a paper towel or something if you're going for detailed areas, so as to avoid puddling.)
I also love the look of the skulls and the bone. Shading and color choice is great here, suits the figure perfectly. The reds are good, too (if a little thick), and those are one of the colors to consistently paint well. If anything, you could maybe bump up the highlighting a step or two more, but I'd say (again) it's a solid figure overall.
