Hello,
I've been working on an arduino micro sd card schematic project for a little while now, just wanted to check with some people to see if the schematic below is correct. Sorry that not all of it is easy to read. Also if you notice the not so clear gray lines in the background, please ignore those, those are lines that I tried to erase, but still showed up a little unfortunately. 
If you have any questions or want clarification on something, let me know. Thanks! 
It looks like the controller is a 5 volt device and the SD card reader a 3.3 volt device. Correct?
I would say it's okey.
