Hey dude! Looking at your most recent pictures, it looks like (in my opinion) pretty standard for the peeling stage, which for me lasts 2-3 weeks (!) depending on the size of the tattoo. It'll look different to your newer one, because your newer one hasn't quite gotten to the scabbing/peeling stage. Personally my tattoos don't get their final "look" until four weeks after I have them done. So my advice would be to wait, keep on looking after it, and calm down!
Of course, your artist is the person to look to, more than someone on the internet. If it will make you feel better I would recommend going into seeing them and what they say. In my opinion though, you're just peeling and it's totally normal! It won't last forever, promise. :)
