Ok, first off, if you want the recording to stand up and you're not blessed with lots of cash to buy expensive mics (I'm guessing you're not since you recorded in your bedroom) then you absolutely must record the guitar and vocal separately.
If you don't, there will always be a compromise getting the guitar sound you want because the vocal has to come first.
Here's what I would do if I were you: I'd go back and lay down the guitar again, this time on its own. If you have two mics available, do as Boydie suggested with one mic over the soundhole and one over the 12th fret.
Then do the vocals using the best mic in your possession. Once you have everything separated, you'll find you suddenly have so much more control in the mixing stage.
I'm really new to mixing, so my advice isn't going to be as detailed as Boydie's or James Nighthawk's or (sorry if I've forgotten anyone!) But I would make it your mission to learn everything you can about the principles followed by mix engineers.
You'll find that these 'rules' are broken all the time by the best engineers, but you gotta learn the rules before you can learn how to break them (IMHBAO (in my humble- but accurate - opinion))
Understanding the role of compression, EQ and reverb alone will give you a much better standing in presenting your track to the world. Don't expect it to fall into place overnight, but by the same stroke, be prepared for a little knowledge to go a long way.
Have fun with it, and let us know how you get on.
