Thats good work so far and shows promise.
I'd say the hand is looking a tad heavy on the wash. This character has a turntable on the
GW site so have a look at that and then look at some youtube tutorial on softening washes or something like that.
I'm a table-ready painter at best, so I'm not sure how I would go about it. Skin can be a sod to get right. Maybe careful work with a fine detail brush to apply a mix of the wash used and the neighbouring lighter colour?
Otherwise, well done.
