I like the light elegance of the Tamarind. Unfortunately, they are not easy to grow in the cold north of Germany, which is the main reason I do not have one. Nice work so far.
The ficus is a fairly 'standard' basic bonsai setup. Nothing wrong with it, hwever, nothing to get overly excited about. I would keep it on my benches, and just improve ramnification and balancce between branches over time. In the tropics, I would probably reconsider the whole tree.
