This pic is lighter than the others, so you can see more constrast. I think the first one's look good, but the wood gets lost in the black background (might be photo only not in person). I think this setup with the add'l plants would have been really good if we saw some of the wood in the middle and lower areas, but overall very nice.
Is the bolbitus in there? That's a tough plant to use in a small space. I used it a couple of times in my Mini S (3.5G), but it was tough to make it work.
