Cheers guys, crits welcome :) Little more progress today. QRemeshed the main head and started adding detail. Need to move onto refining the shape of the boney crown section.
Cheers for the feedback and suggestion :) I should point out that I've not touched the shoulders/neck beyond the harsh ridge and I agree they need looking at. Part of that is I've not decided whether or not to keep this as a bust or turn it into a full character. Will keep it in mind once I'm happier with the bone crown.
