How to Simplify the Interface - What works best

From the feedback I realised I needed to make the interface more simple in order for the trees to be more relative. There were two possible strategies i could do in order to achieve this:

1. I could completely simplify the trees in order to make them easier to understand, they would ultimately just be make out of circles each one representing a different contributing factor to the energy consumption, the colour indicating whether it was a good or bad factor (brown = bad, dark green = great). The user would simply touch the circle to access more information.

2. The other strategy would be to keep the existing tree shapes I have but simplify the legend down so there is just three block colours that are easy to remember, and each tree represents a different contributing factor to the energy consumption however, you would no longer have to remember what each one represents you would just touch the tree to find out more information.

Feedback:

After asking a number of people (both designers and non designers) which one they thought was better, almost everyone said that strategy 2 was a lot better looking and fit with the idea of the forest better. It appeared more sophisticated which would be better suited to the people who ultimately would drive - adults.
