... and I still like it :-))
o.k., edge, so if you're going to have it on your right shoulder, you'll have to consider, this will automatically create some symmetry (sp?) - But (!) having one of the pure line-drawings against you other one with shadows and dark areas, will kill this symmetry. Maybe it's what you intend, but think it over! In terms of 'composition' I'd recommend to avoid that.
if it's only for the Xes (not excess, that is, haha), what holds you back to add to the sujet yourself in combining a bottle that you like (or Xes that you like) with that one. What I think speaks strongly for this one is, he didn't spoil the feet, like he often did when in a hurry!
But if it simply is too 'common', you'd have to look for a totally different sujet, like, say, pages 7 and 8 of 'Dear Mr. Bukowski', where he sits and drinks/smokes. These would also make o.k.-compositions in terms, that, if you use your right shoulder, Buk should look right, like he does in these (again for reasons of symmetry, but also for the composition in itself - it simply goes better having your subject looking 'forward', which is the direction your own face goes).
Or, as I said above, think of another master, more similar to your first one. Maybe have a look at other Crumb-illustrations. He did some on Buk back in the 70s. Or maybe your tattooer is not only a craftswoman but also an artist herself, then maybe she could use one old b/w-photograph as a master to create the style of your other tattoo.
