Yes it's much better than the earlier picture.
The amount of tannins in an aquarium is up to the individual keeping the tank. I personally don't like tannins in water because I like to be able to see the fish. Some people like black water (coffee coloured) and others prefer something in between.
If you personally don't like the tannins or think it's too dark, either remove the wood and let it soak in a bucket of water until it stops releasing tannins, or do more water changes to dilute it.
