Should I ask her out? Go ahead
My biggest concern is that it might be kind of creepy? Accept the fact that to some girls you will be creepy because you made them uncomfortable, unsettled, or feel unsafe. Just because you're creepy to her doesn't mean you are creepy.
I'd also take any advice as to how to ask her out.
If you have the looks then say hi, introduce yourself, and ask her out.
You're most likely going for a younger/much younger girl so it's best to make small talk, show her you can provide stability each time you see her and show off your personality then ask her out that way she's not judging you based on attraction & physical appearance.
