I think I have about 26-29 hours on my back. It doesn't have as much details as you do though. I got what I wanted and then told the artist to fill in the blanks lol.
You should finish your chest and then be proud of what you accomplished! If anything put some....oh dare I say it? dare I? uuuh no but to each their own.
5 days ago I sat 5.5 hrs to get a piece done from just about my knee area to just slightly above my hip bone and its only the outline. I can't wait to show it. The rest gets done in november. Next month I get more work on my ribs too. I have to make more appointments for my sleeve on my right arm but I need to accumulate the funds first after all thats getting done right now. I have the bad habit of starting too many projects at once. woops.
