Profile card component solution

Hello Everyone!! I am a beginner in Frontend world and I am practicing challenges regularly. I dont't understand why my solution looks different on my computer and different when I submit on the frontend mentor. For example for this solution I correctly defined the background positions for background-images and the solution is looking okay on netlify but when I submitted the background positions are distorted and the heights and widths are not the same. That's why my solution image is also looking very different

Please help
