Thank you Grant.
as you noticed, it's not only toothpick, brushes icw dilluters or self sharpened tools that matter when thinking of sculpting.
I sometimes also take pictures of myself, like the fieldblouse of Steiner, to check the wrinkles and folds. Also love photoshop as a tool to compare with original or temperarely add some shades to see what's the painters' job and what's mine.
nevertheless...my fingers are also important tool, for smoothening, moving sections symetricaly.
Not to mention the helpful mirror in time...ofcours faces are a symetrical but a mirrorcheck cuts out the worst mistakes. By rotating subject in mirror I notice it lacks of plasticity and some transitions need to be more flawless.
