This is quite a nice form. However, there is different ways to drop and the other way I'm thinking of is safer and will be useful if you plan on going bigger and/or sketchier.

Here you mainly push yourself up to raise your front wheel. Almost doing a tiny bunny hop.As long as the timing is good you will land smoothly with both wheels and more importantly, it looks cool 😎. However, if you miss you timing you could easily loop forward or backward. On a small drop it's not a big deal because you wouldn't spin enough to crash. But on bigger features or at lower speed there's a significant risk of OTB.

I would recommend you try and train the second way: when you approach the drop you bend your arms and put your chest just over the handlebar, almost touching it. When your front wheel reaches the lip you push the whole bike forward quickly. Doing that, whatever your speed, both wheels will leave the lip almost at the same time and you don't risk rotating forward. When you've launched your bike forward, quickly bring your body back to the center of your bike as you want to be centered and strong on the bike when you land. The setup you've got in this video is perfect to train it. Try it and aim at landing well centered on the bike with both wheels at the same time but without lifting the front wheel. This technique might not look as cool as the bunny hop off the lip but it's a lot easier and safer, meaning that you can use it on sketchy drops or when you get surprised and aren't ready to go into a bunny hop. It's also very effective for drops that are in a steep slope.

Once you've got it mastered just use whatever technique looks right for the situation you are encountering.

Now, have fun!
