Thanks for response. I don't know, i did these reflections as always, fliped car vertical, lowered the opacity, erased edges with soft brush, and for the first time added a filter if i remember correctly / distort / ocean ripple. Haha, headlights are failed at this, because i saw it when i was almost finished the work, so i leaved it as it is.
Sorry guys, I have quite a lot of work to do for school and I don't have much time left for this project. Plus there are other things that need to be done.
