Took a peek at the portrait late last night as I was putting away items to be stored in the studio. It jumps right out at you when you least expect it, that big mistake you have made and not seen all along.
RUT ROW!!! The last finger on the hand hanging down is too short and small. I realized this when I looked down at my own hand, measured mentally the length of my own little finger in relationship to the knuckles and thumb. So I pulled out the reference photo of his hand and of course there it was, but I had missed this. Guess what I am fixing today.
