actually your bucket looks like the compost is exactly in the state that worms want.
I like the worm bin, not to shallow and you can add more material on top with no worry of worm escape over the walls.
Do be sure to check that the landscape cloth is letting the excess moisture through, many landscape materials are not particularly good at letting moisture through as advertised.
If it isn't performing well, poke some holes through the drain holes and the cloth with an upholsterers needle or a thin diameter awl to let that excess
water drain away.
Most of the worm farmers I know like to use shredded news paper, I don't use it and like you, I use ready for worms compost.
