If you love it.. thats the important thing.
Technically - sorry it's very poor both from an art technique perspective and a tattoo technique perspective.
The colour work is really patchy - some of that may be down to ink quality and how your skin reacts, but most of thats down to lack of skill on the tattooists part.
The line work is.. meh, I've seen worse but there are areas there were a thicker line weight would have looked much better - that uniform single weight line looks v amateur.
Shadowing - I don't know if this is poor flash from a book or this was drawn for you/by you, sorry if I offend..
Light source - appears to be from right to left, which means shadows to the left - so the inside edge of the skulls eye socket should be in shadow mostly, and some of it should be the darkest shadow. There'd be some light catching the left side rim of the eye socket. But instead, you've got a big highlight inside the eyesocket as if a light were shining left to right?!..
Then in comparison the snake, which comes out of nowhere.. its neck just starts at that odd wave/water/smoke/whatever... has no shadowing at all, despite there being many areas that should be in shade.
On top of that the skull is an odd shape and the snake being so much larger really makes it look odd.
Personally I would find a decent tattooist to rework this into a larger sleeve - you want to see photos of before and after, cover up work, re-working pieces - NOT just selected images of freshly done tattoos. Newly done ink is NOT going to show up flaws in the tattooists technique.
