Solution:  Skyscraper in 2 eliminates the 2 in R5C3 and solves the puzzle.

It might be boring to some.  But for the rest of us, is it your contention that the cell marked with # can _only_ be a '7' because the other two blocks, marked with *, take awy the '1' and '9'?

Here's how I see it:
 
 
 Take a look at C2 and B7.  The 9 in B7 must be in C2, so the cell # is not 9.  Then you have the XY-wing 79-17-19.  R1C1 cannot be 9.  The only possible 9 in R1 is R1C4, which solves the puzzle.

				Ema,
 
     You actually have a few more of the "basics" that would make your puzzle a little clearer.  The two 9 in block 7 will eliminate the 9 from R1C2.  This will make the xy wing in block 1 easier to see.
 
 
The 9s in block 6 eliminates the 9 in r6c5 but that doesn't make a difference in solving the puzzle. |
