The textures are looking nice

But i might have a little critic or hint: are you agreeing, the textures might show show a too little part of its type? What i mean: it looks like you zoomed with your camera onto a usual texture and now you can see the details - if you see the grass, sand or stones, you maybe know what i mean...
If you build a track with these textures, it might be show loose a touch of realism, since the proportions are not matching so good anymore.
Example: take EasySlider (remember maybe the wallpaper at JGG main page), take the usual tree and houses of the TS 1.00 editor next this default car and imagine how such a texture would look next to the car and these objects.
Surely it is the decision of the author if his track should look realistic or not.
Maybe these textures can even be taken for tracks with cars like Re-Volt or Big Scale Racing, where you are driving with little car models by using a controler in your hands.
Well, in any case the textures seem nice and if people want, they could also resize them to match the proportions a little bit more.
