You were only given one border and you blended that okay, except that you bent it a little too sharply. You gave the grey and red wire to the tile underneath but you didn't really give anything to the right border or the top.
I know there is no-one to the right because this is the edge of the quilt but that's still no excuse.
This tile is from Newbies 10: Practice makes... black lines on the edges of your tile
