That plant is probably not even worth trying to resuccitate.

First, I like the cabinet. How's the ventilation in there?

Okay now your plant and stuff...
Soil- WTF is that soil? it looks TERRIBLE. Like, beyond terrible. Those chunky things on top- if it's gravel, yikes, like soil dug out of a driveway... if it's bark chips, that's bad too for pH reasons.
For your soil you need to start out in a better quality dirt, like seed starting mix from Home dePOT with some extra perlite mixed in for drainage. It will make your life easier and your seedling won't be dead.
Okay, and for a POT, you can use terra cotta if you insist but it is not that great; when you go to transplant the root ball has a really hard time sliding out. Plastic is where it's at.
Size of the pot, it is actually better to start seedlings in a pretty small container, a lot of people use keg cups with a bunch of holes poked in the bottom. I recommend that. Then when your seedling is ready to transplant, it is also ready for its first feeding with real fertilizer.

You are right that overwatering is no good... when you change to a better quality soil with EXTRA perlite added, that will be a lot easier to control.

Good luck... and you must be some sorta genius to figure out how to upload thumbnails with only 1 post... everyone else has to wait until postcount=50!
