Nice freehand! Id made a few darker lines round the eyes and some other places to define it more. For an army it is fine as it is. For showcase I suggest you dilute your paint a bit more and do more intermediary layers to give a smoother finish. If you are doing freehand on paper there's a trick, I don't know if you tried it.. But give it first a coat of a matt varnish (like GW purity seal) it really helps, giving a better surface to paint on. A strong 6! Sven
