Nice work on the lines and really clean overall, not gonna lie - it is huge and i guess 6hrs+ of work wich would be 2 sittings of 3hrs of nice warm needle pain :D
I just wonder how the elbow part is looking when ur arm is idle and hanging down.
I had my share of observing spiderwebs on the elbow that just looked like a shame when the arm is not lifted >.< Thats what kinda turned me off and made it a no-no spot for tattoos for me xD
