Thank you for your feedback, Keith & Recastingspecialties.
To my mind a successful sculpture is a result of many things (interesting pose, correct proportions etc.) but it all depends on what your aim is: sometimes a pose & proportions need to be exaggerated for expressiveness' sake - but this is on purpose and has to be carefully done (one needs to know the rules very well in order to break them).
In regards to mini sculpting I guess that naturalism is the norm and that's fine. I don't think cramming a miniature with details necessarily improves it. Sometimes a few suggestive details can be enough: I realized this when looking at the initial sculpture of my Gordon Highlander - I had sculpted too many folds in the arms and it looked too busy.
I'm working on the clothing now - I'll post more pictures as the figure progresses.
yesterday I started sculpting the clothing. There's still a long way to go as there are lots of things to add: belt, shoes, coat etc. not to mention arms!
As always, feedback is appreciated. Have a good week!
