What exactly is a dutch style? When in comparison to a Amano style?
A Dutch style is more like an arrangement of plants rather than making an imaginary scape. Most Dutch style tanks have a lot of stem plants and do not have a lot of open areas and hardscape. It really is just a tank full of bright, healty plants.
The tank looks good, however I would personally put some plants with finer leaves in to create a sense of scale.
