I think it's interesting to know.
And if you can't estimate hours exactly, maybe say if you've ever estimated hours at all and how many days and weeks it takes to finish one piece?
 


I will start, this is what I remember, this took 30 hours and it's a pretty small portrait and it took a few full days to finish it, because I was in a hurry


otherwise, I wish I had written the hours down also, so I could keep track of time
