Puzzle #54: Sum Skyscrapers

Of course I needed to add some Latin square based puzzles. I also tried to fit in some arythmetic based puzzles in there. Sum Skyscrapers have always been my favourite variant, so it seemed like a logical addition.
The first puzzle I tried to make the clues on each side to add to 24, except how much I tried I couldn't get it right. This was the nicest result that came out of the attempts.
The second puzzle is a harder one. I was really happy with how this one worked out.

In this variant the numbers on the outside indicate the sum of the visible digits.
