I still think the colours used are still going to be a problem. The high contrast dark colours with bright cyan text doesn't look great. The text (cyan coloured) is a little blinding.
Going into the threadlist. The colours are really set at a high contrast and I can see people with sight problems won't like the colours used, and to be frank, the colours and gradients really strain my eyes.
I'm not to keen on the colours at all. I would also replace the default stock images and replace them for custom made variants but I would seriously work on the style some more. I'm not a fan of dark styles but I've seen some nice dark themes. Unfortunately, this isn't one of them and I would find it hard that this would appeal to alot of people.
Goodluck with your site regardless.
