But there is a problem, my left shoulder is tired and the muscle in the picture hurts. I only can practice 10 minutes before it becomes unbearable.

Interesting, is this muscle involved much? It supposed to move the shoulder upwards/backwards, right?
If you hold guitar in clasical position and drop shoulders - relaxed - then drop arm straight down, palm forward. Then bend arm at elbow so palm comes to guitar fingerboard. In this position hand will be around 6-7 fret. To reach 1st position you need to move hand towards guitar head and this uses muscles in the area you mention. Also, if you push your elbow forward, again muscles in same area. Check you are not holding tension when you move hand to head of guitar. Also if you need to push elbow forward try to do it by rotating from shoulder rather than pushing shoulder forward.
I had discomfort here when I changed sitting position, I found that moving the guitar head closer to my shoulder - guitar more of an angle across body - worked to relieve arm/shoulder stress.
Try experimenting and see if you can find where you are holding tension.
