Well, I wouldn't call it great. There are many problems with it.
-- 1.)It is way too symmetrical. The builings could be arranged a little better by not having them perfectly symmetrical.
-- 2.)The buildings don't look right. The PC, Mart, and Gym are blurry, and the lightest color on the roofs of the houses is too bright.
You should also say you customized the buildings, not made them. Making a building is making it completely from scratch.
-- 3.) There are many tree errors. Look behind the PC and Mart. The FR/LG and Silon trees should not be mixed. Also, look at the lower right tree near the fountain. It is covering a piece of patch.
-- 4.) The lake doesn't seem right. Mak it smaller and get rid of the fence. Use rocks instead.
-- 5.) There are way too many flowers. Get rid of about half of them.
Other than that, it looks better than your other maps. 7.5/10.
