The look is fine (I would probably make the grid a little less prominent), but the layout is so linear... ;)
I'm digging it. I've started creating maps that are a bit more straightforward (linear) just for ease of explanation while dming. What program are you using? What i've done latetly is draw a map on blank white paper no grids, then scan it touch it up and add a layer of grid underneath, due to not having the grid to start off with, its interesting sometimes where it ends up. some lines will be in a middle of a square etc.
Been using Inkscape (a free, open source vector art program), Photoshop CS2 (my college edition I got in college) and Google Photo for that effects. There is a tutorial I need to link that I've been using to learn it. It is a little cumbersome at first but gets very good later on.
