Dave nice work . youhave a continuus improvement as you paint a lot lately and that surely helps . Things i would give a second thinking on the figure :
1. More contrasted painting on the base stone piece ,especially more shading tothe inner sides
2.At the distanceyouhave picturedhim , face seems tobe more whitish than may be needed. And maybe some more degrading of the shadows wold help to give a more variable result.
3.The upper area of the wrest arm seems to be uniformly colored , soit couldhave some more degrade of toning
Shining doesnt help a lot to cast more detailed opinion, but since you do good works lately, i thinkwe mayhave tobe more precise in our commentation to help youlift even more higher.
Keep Safe mate
