The perspective of the house seems a bit strange, and the fence itself looks a tad too thick.. but good idea. I like the use of the original background for the sky.

the shingles on the roof (patchwork filter?) don't follow the direction of the roof and it throws off the perspective; you should use a marquee to select that part of the image and make the shingles meet the slant of the roof; then cut the roof back to its original shape.

If you were going for something like a frame off an episode of "Southpark", I'd say you nailed it but it looks a lot like cardboard cutouts. Looks too simple.

cute

very cute illustration.. good luck!!!

heeee... sorry , "little house" where we live means.. TOILET. maybe next time you may like to use grid lines etc in photoshop or whatever program you use as they may help you get perspective and structure of your image visually correct. I like the image overall and i like the use of source. GL

nice
