Hey Sweetiele,
Thanks for sending in the video that’s great!
Firstly looks like you’ve got some good solid strokes there and also a lot of potential to improve. So a couple of things, your getting a good acceleration on both forehand and backhand but your arm seems quite tense especially on the forehand side, so try keep your arm relaxed as you play the forehand and use slightly more rotation from your body and waist. If you can keep the same acceleration but have a smooth relaxed movement it will make your forehand even more dangerous.
Also with the forehand when coming back after playing a backhand your bat tends to drop slightly down, if you can keep it a touch higher it will help your efficiency and recovery between shots.
With the backhand, your technique is looking very good! Again when switching back to the backhand if you can keep your bat a touch higher and keep that nice brushing contact and use of the wrist and forarm you’ve got a good solid stroke there.
Keep up the good work!
