Inspirations: Ugolino and His Sons

I used to love going to the museum and sometimes taking in the art. Other times I would site there and actually start drawing it. Here is an unfinished piece I did in 2006. I have not gone back to finish it but I would love to. It's just been hard to find the time to do it lately. So, the last time i went to a museum was 5 years ago. Is that sad? What do you think, should I finish it or start it over?

You can find "Ugolino and his sons" by Jean-Baptiste Carpeaux at the Metropolitan Museum in NYC.
