Where do I go next? I'm new to challenge/expert level sudoku and don't know many techniques past the hard level and am truly stuck. Please explain if possible : r/sudoku

Would a sudoku expert kindly help me out here? Is this the correct use of a skyscraper for 6 in (r3c3, r7c3) and (r1c7, r7c7) to eliminate 6 in r1c2? Thank you! :
