Nick, et. al.

Would love some feedback on the tiles.
http://home.braddock.com:28112/osm/slippymap.html

The scheme I've broadly followed is this:

Zoom <= 6
Natural earth data overlaid with text labels

Zoom between 7 and 10
OSMBright as a base layer + hillshade + slopeshade + color-relief. DEM data
is SRTM 15 arc-sec resolution.

Zoom >= 11
OSMBright + hillshade + contours. DEM data is 1 arc-sec resolution

Would LOVE feedback, critiques on the design styling and suggestions to
improve it. For example:
1. Contours at zoom level 11 is maybe a bit overdone, can be included from
zoom 12 or 13 onwards.
2. Between zoom 7 and 10, the tiles look faded. This is primarily due to
the hillshade, which is gray in color. Now if this is really a problem, I
could make this situation slightly better.
3. Zoom level 10 (the last level with the crazy colors) has too much faded
out elevation, and in the next level the elevation features are much
sharper. Is this a problem?
4. The colors of the contours is blue. Maybe there is a better color out
there? I suck at design and colors generally!

In terms of size, the tiles with elevation data are roughly double the size
without elevation data.

Thanks everyone for being a great help during this process. :-)
