Beautiful Horses - InsertCompleted by Marion Harding Crafts

I made an A5 card. I printed on to 160gsm. I put double sided tape on to the left side and stuck to the inside of my A5 card blank. I used the corresponding kit for the front.

I would like to note to the designer to look into the image because it appears to be stretched, as in that it's not in the correct picture format? Could this be rectified? This is the same for the rest of this range.
