Good start man! And good luck, can't wait to see how it turns out. Dutch tanks are my favorite handsdown. But I threw in the towel. It became too difficult to keep all the plants happy when I had it densely planted. The lower parts of the stems would suffer. From a thread I started on PT, folks suggested this has to do with circulation. When growing plants so close together circulation is a very important factor (as is lighting). The lower parts of my stems were losing leaves and getting algae, while the tops were doing great. Finally got fed up and tossed a bunch of plants. Going for a super simple scape now, just two plants; hygro and blyxa.
Can't wait to see this tank in a month or two
