Best thing about your action is a strong front leg. However did you know you bowl with a mixed action? Back foot lands side on and you look inside your non bowling arm, so front on. Need to get that sorted ASAP not just for performance but also for injury protection. It seems you lean back in your flight phase, when you want everything going towards the target/batsman. When you land your front foot if you were to draw a line front your back foot heel to through your front foot heel the line would be pointing towards fine leg. Again you need this to be pointing at the batsman. What that then makes you do is add lateral force to get around your front leg t be in a squared on positin at relapse. The ideal is knees, hips and shoulders square on to the batsman at release. Evidence of this lateral force is you falling to the off side and your follow through to the off side, again needs to be straight through the crease towards the batsman before tailing off the pitch.
Now initially this seems a lot however I believe if you sort out your feet this will have a knock on effect for the rest of the action.
Does look as though you have a good wrist positin which I suspect makes the delivery look good and get bounce but there is more potential not being realised.
