I didnt realize how crappy the original Losail look and feel was until i tried this one...
Only issue is that the tyre marks, skid and brake marks, on the original a pretty well drawn (also commented with other tracks you made). Here they kinda look like water marks. I dont believe they need much tampering from the original. New kerb colour is cooler and generally at least now the tracks is alot less cartooney!
The rubberizing I was trying to achieve was the dirt, you can check here a comparison: http://image3.redbull.com/rbcom/010/2014-03-23/1331641207416_2/0010/1/1500/1000/2/marc-marquez-valentino-rossi-motogp-2014-qatar-red-bull.jpg
