this map does not look bad at all. so far i considered most st:mudrunner maps as sub standard compared to well done spintires maps.
but by now some are surely worth a try.
my 2 maps for spintires( not st:mudrunner!)
http://spintires.nl/level-styx/
https://spintires.nl/level-wilderness/ (i convert this for mudrunner but did not release it)
both are log maps only, exploration is less of a thing on my maps.
