so you say this is your first map? if so its quite a good start, the way i wortk when making a village like that (not saying its the best way or the way others work) but i will get teh terrian done that it will fit around that means things like cliff faces rock formations and the like, also suggest not useing grass. . . .
then i would of already started with a picture of a bit of it in my mind i'd biuld that bit then keeping the same theme id biuld the out line to a small village then id go over it adding the smaller parts and more detailed bits and just expand till i decided its big enouth.
have fun. . . . thats whats terrianings all about . . . . if your not having fun then its not a good map . . . xD
EDIT: also try not to streach dodas noticable if you do it do it subtly its just when textures get streatched its easy to see and dont look that good
