Up until recently I haven't done extractions. Really I've only done 3. I've extracted a few things for sigs before but it's typically only specific areas I need.
Well here are my first 2.. The Gumi one being the 2nd one and Rin being the 3rd I've ever fully done.
The third one is the one I spent nearly 9-10 hours on. I used the pentool for it. The 4th and 5th were more practice.
