I'll echo everyone else. Don't sweat it. My first tries were pretty sorry too. You've got a mini-tut above for how to post images...so start a WiP thread and post your attempt. Maybe we can help you make it better.

Also, if you're just not getting the software, don't fret too much. Get out your pen and paper and have a go with the good old fashioned way. I wasn't having a bit of luck with Photoshop on my city map, Haibianr, so I got out the drawing supplies and just did it, scanned it, and colored it. It ended up being a Cartographer's Choice. Believe me, if I'd stayed digital with it no one would have given it a second look!
