I think the styling and text of your page are fine–the biggest concern from me is how those juxtapose with the screenshots.
Having a description that talks about ‘awe-inspiring landscapes’ and ‘breathtaking vistas’ next to screenshots of relatively flat green land with samey low-poly plants and what appears to be a very sharp edge of the world with a default Unity skybox in the back is not a good look for your product, and I think if you want your game to stand out more your best bet is to make it visually stand out more.
I suspect you might realize this already, at least subconsciously, since you tossed a caveat at the top of the page about coming updates. Imo it’s going to be tough to sell users on a promise of what you want the game to be, I’d still advertise (you can never start too early) but focus on making sure those updates that complete your vision actually land before worrying too much about downloads.
