Excellent review, Dave - on an excellent figure. Mike's sculpting catches the finer points of the subject in this and in other subjects. The awkward folds at the bottoms of MvR's sweater (or jumper - for you UK folks!) are beautifully rendered. I have to say I agree completely with your assessment of the "natural relaxed poses" that Mike is able to achieve with his work, very much shown in this example.
Any figures I've bought from Model Cellar (quite a few) have been a great investment in the final display of the projects I've completed.
Cheers,
Gary
