Huh...this is quite the interesting idea. A symbolic patchwork heart...not something you see too often, not like thats a bad thing.
Its actually quite nice, hehe. I am curious, did you use basic color pencils like Crayola or something or artistic colored pencils?
One last thing, when using colored pencils, pen, etc. to fill a drawing, try to do strokes with the same orientation, makes it look a bit smoother. Still, nicely done, my good sir.
