Seconding "go to a professional", and by professional, I
don't mean a salon.
I know being young you may balk at the cost of going to a professional piercing studio. Yes, it's usually way cheaper to go to some salon with a gun. It'll probably heal ok, too (since it's only ear lobes).
Guns are nasty. They were designed for tagging cattle, and in my opinion that's the only thing they're good for. For starters, the plastic they are made from cannot be autoclaved.
How they work - they ram a stud into your ear lobe... a blunt stud. It causes much greater tissue trauma and creates a rough and nasty hole compared to a proper single use needle. Also - those cheap studs the guns use are normally of pretty sucky quality both in materials and machine work.
Bad machine work on the metal and jagged piercing gives bacteria a place to hide, promoting infection. Rough holes take longer to heal and can do so with more scar tissue.
More often than not, the studs used in guns aren't long enough to allow for swelling to happen and drainage while everything heals (which increases the chance of infection yet again, and make it a literal pain to heal and keep clean).
Find a nice place that uses single use needles, and has an autoclave onsite. When it comes to body mods - do it once, and do it right.
As for tattoos, I'm going to have to go with the majority here and say that the face tattoo might end up being a very, very bad idea.
The dragon face tattoo that pic is a fake anyway. How else would she be wearing layers of foundation, blush and other makeup and have her tattoo still look so vibrant?
She's got enough caked on foundation to cover quite a few pimples - it'd cover a real tattoo for sure (at least partially).
But hey - if you like the look, then that means you can replicate it using makeup just the same as she does
