Did I waste my time adding the footer animation on my site https://forge.co.nz/ Someone who frequently visits my site told me they’d never even noticed it.
I suppose if you spent hours and hours thinking it would make a huge difference, those hours might have been better spent.
However, I like the wave animation. Even though little things might not be consciously noticed, they’re still seen and add up to indirectly communicating one’s attention to detail, which is a positive attribute for a designer. Maybe you could let it run three or four seconds longer, if you want it to stand out a little more.
I fully agree with @Just-B.
Slightly off topic: for a few brief moments, there is a font glitch (Safari browser) which may not be intentional. (white extra-light text on turquoise text)
