the blending is very nce and i like the colors. however i think that the outer edges should be a tad softer, rather than a solid line where the shadow ends. but other than that i think you did a lovely job!
i love the blue one! i agree where your eyeshadow ends (in your crease) it could be softened alittle so it fades out upwards. but the colours are very well blended into each other.
