Looks good.

As for the dirt colour, it looks like a reddy clay to me so if that is what it is supposed to be it's great

Looks like a good start, the mixture of grass tones and earth showing through is great! You could perhaps improve it by making the centre strip narrower, or the ruts wider - unless it's a really new track I think the vehicles would have wandered around more. I also think the colours look quite saturated, but that might just be the pic. I'm not sure what you could add in the way of fluff and details - maybe some weeds and a few stones crushed into the earthy bits?

e.g. http://www.photorevisions.com/images/Photo_R/KL%20church2%20dirt%20road%20lr%20P6091192.jpg

I was thinking of using some small bits of ballast and traditional scatter in the ruts, and maybe some powders too. I should have done that first, but you know... scatterbrained here. As far as the width goes... it's the track to the signalbox, so gets used by two vehicles a day each way, assuming an early and late shift.

I've taken care to mix tones a bit, adding some of my shorter strands of varying colour in with the longer monotone spring grass. I'm going for a late spring lush look, not exactly fashionable, but attempting to match the backscene. And the colours in that pic just don't match the reality- I tried various white balance settings, but none seemed to match entirely.

Powders sound like a good idea. I don't think it'll be a problem to do it second, if you squash a few bits of grass in the process that just adds to the variety

The static grass works really well here, I like the way the strands lean over into the track. Looks proper tussocky.

I think the middle would probably be narrower but it's an excellent attempt and a great representation. It shows the difference a static applicator makes over the puffer bottle I've used. Does your camera have a manual white point adjustment?

I'm really impressed with my homebrew grass applicator, and I've only had one belt off it so far! It just works, and I do wonder why I put off making one for so long. I haven't been doing large areas in one hit, but I am surprised how far away from the earth point it actually works. I've started clipping the eart to a rail (not with trains or controls attached) which avoids the need to pin into the scenery.

As for the camera, I've tried manually changing to different white balance settings, eg daylight cloud (the picture was taken using natural light), but something just seemed to confuse it. The Range Rover is actually maroon!

The white balance in that pic doesn't actually look too far wrong, I corrected it off the number plate and it didn't make much difference, although that's fairly bright so it may have been clipped. You could always put a grey card at the edge of the picture so you can correct WB on the computer then crop it out afterwards.

More importantly, does your camera have a saturation option? It's sometimes disguised as "colour: vivid" or some such. If so, turn it down

I think the track looks pretty good as it is, it looks like a little used track rather than one in regular use. One thing that I'd be tempted to add is a few hollows with puddles in them.
