I gather that this is your first week at it. Have you read the books? Have you watched the videos?
You are really slender. You must eat if you wish to get strong.
It is difficult to get depth with an empty bar. Your hips are not at depth.
The bar looks too high even for a high bar squat. In fact it is so high it is a danger to your neck.
Read the 3rd edition of Starting Strength at least on the Squat and then try some more and video tape them.
More comments later.
