Listen: get real. A building isn't just one shade of red. Stop using MS paint to do your skinning! It will ruin your model. It really doesn't matter how awesome the model is, if the skin sucks crap, the model sucks crap.
I recomend getting Photshop (or if you have it) play around with it and make the skins worth something.
By normal standards: They deserve a 1 or 2 out of ten.
By Naruto Model Standards: They deserve a 4 or 5 (that shows you the quality of ALL naruto models. I have yet to see a GOOD naruto model.)
