Did I develop impending scars after laser tattoo removal? (Photos)

I have had my first laser tattoo removal treatment with a ND:yag laser 4 weeks ago. During that session, two tattoos were treated. The one on my back did not blister and has already healed. The one on my arm however is very rough to the touch. When I have a really close look at it seems that there are tiny holes visible. The skin also feels pretty dry. There is alsof some browning. Will this heal if I give it some more time of what should I do? I'm pretty anxious about this.
