Hello,

Actually I think the cut/blend looks pretty good in the pic, I do see a slight wave to the piece as you mentioned but looks natural to me. You might want to thin the edge out where it meets your own hair with a razor comb. What I do notice is that the color seems a bit off, your hair has red tones in it, and your piece looks very ashy (no red tones) in color. Thats an easy fix.
