Hi guys,
I am making a wordclock with an LED matrix, please check the schematics for any mistakes.
Thanks!!

I don't see why it wouldn't work.
alright, thanks!
I just wanted to get sure because the board will already be etched on friday
WAIT, did you test it first? Just because I don't see anything wrong with it, does not mean there is nothing wrong. You always need to test and re-test first, before you make a board.
I'd be e bit worried about the current-sourcing ability of the '595s, they really aren't designed to drive LED statically and if you're multiplexing you need more current than usual. IIRC they can source maybe 6-7mA, check it out.
You may find the LEDs won't be bright enough.

That's why I have the Darlington Arrays

For sinking the rows, it's sourcing the columns I'm on about.
You know there are single chips that do this and more, for example the AS1130.
