Ok here is my 3/4 sleeve.
Completed on the 23rd of december. Took 13 hours over 5 sittings.
These were taking after my 4th sitting (a nice 4 hour one). My final sitting i had some dirty shading put on the cards to blend them in a bit more and some powerlining done to bring some of the bigger pieces out a bit. I havent taken any photos of that yet.
It's all black and grey. The bits that look redish/brownish are just the swelling and bloody bits from just having it done. Please ignore the pen marks that i hadn't washed off as well.
