That's good. Ideally you want the evaporator pressure to be as low as possible without the compressor cycling excessively. Lower pressure means lower temperature and then colder A/C. Adding any more refrigerant will raise the pressure (and temperature) of the whole system.
The only trouble you might run in to is the fact that your system was pretty much empty and you never drew a vacuum on it to get rid of air, non-condensable gases and moisture. They add pressure to the system and again cause it to get run at a higher temperature. Since you didn't fix the leak, you'll be doing this again sometime too...
