Some basic things that go with the semi-western grip forehand:
Stance: Open or semi-open
With the taking back of the non-hitting arm, complete shoulders' turn so that the right shoulder is at 6 and left shoulder at 12 o'clock positions; the racket head is higher than your head and in a loop,
the racket descends, get below the level of the incoming ball, and then rises to meet the ball out in front and at chest height, if possible,
If your hitting position is behind the baseline the racket will finish over the left shoulder,
however, if your hitting position is inside the baseline the racket will finish below the level of the left shoulder. It all depends on what you like to do with the ball.
I gave you some general characteristics of the semi-western forehand because I can't see the vids because YouTube is banned in Pakistan.
