Spline Landing Page Design Enhancement

I’ve already built a basic landing page in Spline, but it still feels a little rough around the edges. I’m looking to tighten the layout so elements line up intuitively, match with my references, and have sick typography.

I'd also like to introduce some tasteful interactive elements and lightweight animations—think subtle hover states, scroll-triggered transitions, or micro-interactions that reinforce key calls-to-action without overwhelming performance.

This should be a quick, simple project
