Lovely artwork!
In Japan, it is more common to have 3/4 sleeves (if you even have tatoos). And without a doubt, a man's watch is akin to a man's prowess/virility We take things very seriously, if u catch my drift.
Personally, I like full sleeves. But I would only go 3/4 due to my watch-love.
Hey, this is just my opinion. Who cares what I think. You have to do what you want to do.
Cheers
PS. Going to Ito in the summer at the beach is a real treat. There are lots of young roosters showing their favorite Buddhist Sutras manifested upon their backs - full-size Buddhas. Never in color either, always black ink. And as always - done by the best of the best masters in the world. You can tell, too, from a kilometer away...
