Would it be improved if the various sub-panels were not all in the same color theme? Also, symmetry is nice but clarity is the best in design. Perhaps the gear selector, MPH, ACC and MPG should be merged into a central main "guage" and then fuel, temp and power levels off to the left. The leafy zone would still be to the right but a bit bigger and with no distracting elements up against it.

In summary, this looks line a design by Microsoft and it would be more appealing and easier to use if it looked like it came out of Apple's design studio.
