Help , I’m a tattoo beginner I don’t know what’s wrong with my tattoo

I got my 3rd tattoo last week and I’m not sure what I’m doing wrong , I moisturise 2/3 tines a day I keep it clean I don’t touch it and I keep it out of sun but yet there seems to be some ink withdrawal and some of the ink hasn’t stayed in the skin Ive provided couple of pictures, please help 

everything is much appreciated 

what do you guys think I’ve done wrong or is happening with my tattoo
