It’s not particularly well-designed or executed, but it’s not awful either. It could have been far, far worse. Considering that it’s entirely in black and gray, the outlook is great for laser removal. I think the piece is too big to simply cover after a couple laser sessions, so I would recommend going for a bunch of sessions and removing as much as possible. Make sure you choose a reputable place to do it.
Regarding the itching, you’re likely to have that with any tattoo if this one bothers you. I have 3 tattoos: one in black, one in B&G, and one in color. All 3 are from highly regarded artists who use quality inks and yet the only one that doesn’t itch is the solid black one. The itching is minor and I don’t break out in rashes, though I do frequently get some stray bumps on the color one. FWIW, the two that itch are both on my upper arms like yours.
