Social Proof Section Master - Challenge - Using Bootstrap

This one was really a challenge to me. Any feedbacks are welcome. I had some difficulties with adjusting the purple comments boxes, I couldn't adjust all in the same line with the levels between, read some articles online and could applied but at the end the level diference it was really big, I really need some help with it, if anyone have some tips, I'm really glad to read it.

The mobile design end out fine when I saw it on my phone. Desktop design had this issue with leveling up the boxes.
