My piano teacher has told me that my fingers bend in an unnatural way and this will be detrimental to my long term piano success. What are some good excersizes from prevent the tips of my fingers from laying flat on the piano and instead having arc. Here is my attempt to show you how my fingers hit the keys vs how they should hit the keys.
How they should hit the keys (at an angle)

How they hit the keys right now

the first joint in my finger goes flat to the piano which I have been told is bad for my form and sometimes can hurt to play. I don't have this issue EVERY time I hit a key but sometimes I end up hitting the keys this way and I want to not have issues in the longer term of playing the piano.
Any advice will help me greatly, thank you for taking the time to read this post. EDIT: any specific practice routines specifically will help me so much if anyone has resources for this issue, thanks again.
(ALSO, they angle is obviously pretty dramatic in the slashes but I hope you get what I am saying)
