That's what rpgmapshare is for; no need to apologize for that!

rpgmapmaker has generously shared a number of Photoshop brushes, including some compasses here: http://www.cartographersguild.com/showthread.php?t=2078

You might also browse through the Mapping Challenges forum, as there was a challenge last year to create a compass, and some very nice pieces of art were submitted there.

You've got a pretty good start on your map already. The buildings don't look like they're quite part of the environment yet. A bit of shadow would probably remedy that. The easy way is a simple drop shadow layer style.

Remember to try to have all your shadows pointed the same direction. I see that the grey building near the bottom of the map has strong shadows on the north-west side, but there's a rock that is shadowed on the south-east. Obviously, it's probably easier to rotate the rock than the building, so I'd operate under the assumption that the light is coming from the south.

Welcome to the Guild, and I hope you enjoy your time here!
