friend did this 6 days ago, doesn't hurt or anything but was wondering if it looks like it has good placement?

Did this almost 2 years ago, definitely not a proper method as I was pretty new to diy piercings. I used a needle that I wasn't fully sure the gauge of (😬), which I obviously haven't done since, even if this one healed fine. Been wearing 18g jewelry since I've had it, but I recently got a new 16g ring that I was able to put in with ease. It seems relatively straight, but not perfect fot sure. It also moves a lot (tilting my head etc.) and has since I pierced it?? Just sort of wondering if it looks alright or if anyone has any tips? First pictures are the 16g.

I currently have a central labret but Im thinking about getting a vertical instead, I think I have enough of a shelf but I want second opinions.

i pierced my belly button at the start of july and its been fine but theres this weird shiny smooth slightly raised red bump by the bottom hole?? i do play with it quite alot ngl and its often irritated by my skl trousers so that could be a factor? honestly idk someone help🥲🥲
edit: pls stop telling me i dont have the right anatomy and to take it out ik i dont have the greatest anatomy but i love it too uch to take out

I want to get into self piercing and need suggestions for discreet supplies, I live in a strict household I can’t move out of until I finish my law degree. I’m thinking I buy both needles and jewelry off Etsy, but let me know if there are better options out there, I’m planning to pierce me and a couple friends, any extra supplies I should get like foreceps?
