Step 8: Completing the fingers
The thumb underwent a lot of resculpting until I was happy with its shape. One perk of using snow as a sculpture medium is that you can add to and subtract from it as much as you want (unlike, say, a block of ice from which you can only subtract). The downside of this is that it's easy to getted bogged down in perfecting the details when you don't need to get them right first time.
I wasn't confident that the palm would support my full weight, so I resisted the temptation to climb onto it to sculpt the fingertips and fingernails. I stood on a chair, but large snowballs also make handy stepladders.
Because this sculpture took several hours to complete on a cold and windy day, the lower parts were frozen very solid by the time I came adding details to the upper parts. This mean I could have the fingertips and thumptip slightly overhanging into open space without them collapsing.
