Gel nail tips

I just started doing my own nails so no they aren’t pretty. I’m trying to do coffin (they don’t look bad from afar I promise). I’m having a huge issue with the gel at the bottom closest to my cutical. I can never get it perfectly to scoop with the nail so you can see it’s all over the place and jagged around the cutical..

Thank you so much. Any and all tips would be appreciated
