Note:
Since normal maps don't capture back faces, you invert a
shape and it will show up in the normal map as an
indentation without you having to worry about all the
edges you'd have to add to support an inset surface. This
is possibly the biggest time-saver of my day. This is strictly
used in game art though; it absolutely would not fly at a
film studio.
I added a little more detail to the cylinder element at the top
of the panel. I also reused this element in the lower part by
creating three instances, scaling them down, and putting them
in a triangle formation. I also added more detail in the back-
ground with some flowing lines in the gaps where you could
see the flat and boring background. Finally, I added an inverted
shape that echoed the shape of the lower panel.
