I can only help with some pointers at the moment...draw that lake and that peninsula...this will get ya moving. Put a dot where you want your castle/fort to be...then draw some roads that radiate out from there. Draw some rough shapes for where you want the districts (nobles, merchants, peasants, etc.). Put some roads thru those districts then put some more dots down for important places in each area with roads that go around or radiate out from said places. Once this much is done it's nearly finished...just pretty it up. If you need an actual drawing to get you started because you're at a loss for everything...well, then ask someone to draw ya a lake and you can take it from there.
