I know generally it's wise to finish the sleeve with hand tattoo but... 🙂   I wanted tattoos for long time and decided to go first with the simple ones I guess, like I remember wanting a dice tattoo on my hand thats it, I also wanted to cover the scars on it. 

It's a pair of dice. It's basically flash. Don't worry about it. Also, why did you get a tattoo on your hand? You appear to have very few tattoos otherwise. Just curious.

Things happen. Hassling the artist isn't going to make him or her in a huge hurry to get back to you. Just leave it. Let them get well. There are lots of bugs going around at the moment. Also, they did YOU a favor by not making you sick. So calm down.
