Fully responsive PC and mobile version, SASS, Fully working Javascript

Hello, I have a few questions and I would be glad for some tips. I made a fully responsive CSS, even for small screen like a 200px the image is scaling. I think I did overall good job in responsivenes. Javascript I would say its pretty decent too. My question is, if you can position the images different way(better way) than I did and if you can make scaling better. I used this top: 0; left: 50%; transform: scale(0.90) translate(-53%, 10%); They have same width using max-width to scale in the same time and if I need it bigger I used the scale to make it bigger.

Any tips to improve? Thank you very much.
