Experimenting with texturing I drew a planet with continents and scanned it in, then highlighting all the continents and spherizing a planet texture over it, and vise versa for the sea, the results are interesting:
Multiple variants of texture, colour and cloud density.
Comparison of scanned image with finished result
The next step would be to animate the planet into a rotating GIF, but working out multiple frames for the planet turning is going to be tricky, will update if any progress is made.
