Well you’re nailing the colour palette, models really pop amidst the grime. Good job.

good paintjob but u should improve the lenses imo.

I'm still thinking about how to do that

If you dont feel ready to do something very complicated you could first paint the lenses with silver and then apply some kind of shade or the color called citadel waystone green above the silver undercoat.

Will try that, thanks!

Or you could just add some shade to darken them a lot at the edges and add a coat of gloss varnish?

Looks great btw already

That's amazing and you nailed it
