Very charming =)
I agree about some color inconsistencies. The far buildings don't work: either they're too bright for this sky, or the sky is too bright for them.
I don't get the multicolor roof either.
You mostly have a really good grasp of the pallete and make a lot of good hue shifts, but there are a few offenders - the worst being the blue shading on the woman's dress. Also, the colors shift from warm to cold without much rhyme or reason, confusing the eye.
All in all though I think you're on the right track with your use of color. The experimentation is admirable and the composition of the image is quite good!
