Profile card with SASS

My biggest issue regarding this project was getting the two circles just right. I managed to get them as close as possible to the image but I am still not satisfied, furthermore, the bottom circle expanded the width and height of the screen for some reason and the only solution I found to fixing this was to use "overflow: hidden;" on the body element.

I am curios to hear any suggestions or advice on how to better position the circles and what is your prefered method of quickly getting the position right when it comes to these off-screen images.

Thank you!
