5.5 roughly, I will just give you what I see. The cloth looks like here is some shading and highlighting, the bone needs a bit more variation, such as an inkwash with highlighting after, the yellow is a tough color to deal with in the first place. The base has a great start, but put a light base coat on the sand and then drybrush it in variation, dependent on the type of rock it is. Metal is hard and am sure that there is a great tutorial on "paintrix miniatures", a website that has tutorials on differesnt things. It is done by a GD winner. Hope this helps some. Good luck and keep on painting!
