Ill use the track im making rn as an example (the track style may not be exactly the same. But add things that fit the surroundings. Yours seems to be offroad, whether it be super dry or be in the mountains both have nature around them. Take mine for example, yes I know my detailing isnt the best, but I have added grass and flowers and plants around just to make it fit the track better. Or if you dont want to do plants you could do rocks or other things like archways, or gates or whatever that fits the track, use your imagination! You could also add trees and other stuff! I hope this helps, let me know if you have any questions. And remember nature is random but random at the same time, my friend Fluffysmack once told me about how plants grow towards the sun and not all trees are the same etc etc.
Don't forget you can always screenshot something and post it on here asking people what they think and most of the time there will be somebody who gives you a tip!
If you want to draw trees or grass I recommend using the brush but slow the speed of using the brush. Also alway use gray lines as a outline before you draw a building or cloud etc. Remember you can always erase the gray lines over black lines but only select the gray lines for the eraser.
Really it’s just practice. I would recommend looking at how some of the more famous authors draw trees. https://community.freeriderhd.com/threads/fluffys-how-to.14126/ http://frhd.co/t/269042-garden-gypsies-reprise I’ll give you some of my tips if you want them.
An old layout I made that was originally supposed to be for rcxr1 that I never finished but still really like the potential and would like to finish. If someone is willing to take the time to dm me and play test for kinks, rough spots / truly annoying areas, or for any comments related to the track, that'd be wonderfully accepted. The goal of the layout is to be a nice little challenge for intermediate riders and a ghostable, smooth track for expert riders with a wheat field / overgrown meadow theme.
