Hello Virginia,
I too have trouble using Photo Shop. Every time I use it I do learn something new. Just a thought. Eric took the photo and did 180 degree turn and gave you a different perspective of the reference photo. If you can't do what Eric did, try looking at the photo in a mirror. It works with portraits that seem to be off and you just can't get it right. It gives you a different look at the composition. The mirror will work wonders.
You have some great advice and input. Good luck.
