Hi, I'm not really sure about the colors and gradient.
I would advise you to make the blue background a bit different.. make some showcase research and see what could fit better on that background.. maybe a more linear and brighter blue with less gradient.
The downside of your design is definitely the brown form! I would remove the gradient and change the brown for sure.
For last but not least, on this kind of page, I would make your image/video and form with rounded corners, give it a shot!

Thank you!
