AK Interactive's Deep Yellow has worked alright for me, as long as you start with a white base, it shouldn't take more than two thin coats to get an even coverage.

You're pretty good! I'm a bit amateurish in comparison, but I'm getting there. Do you use an airbrush? I'm not sure why but looking at your models I get that feeling, though I've never used one myself.

I ended up going for a mix of lens colors in my army, Mephiston Red works as a "basic" eye color, but I'm now also using Vallejo Flourescent Magenta for the eyes of warp-creatures like Sorcerers and Obliterators.

Just saw that! (not used to Bluesky's UI just yet so I didn't know about the alt text stuff)

Zealots is great, and seeing the details on some of your army, I'm pretty confident in saying that you have a comfortable list there!

Are you running an OC warband? If so, how's the paint scheme?

Maybe a bit character heavy, and I hear Helbrutes are a bit mild nowadays, but it's certainly usable!

What detachment are you using? The list seems Infantry heavy, so Creations of Bile might work well.

I'd hope so, I'm quite literally trying to sell one for $200 AUD.

(Soul Sacrifice Delta was its best game btw)
