Landscape With Truck

I got started, but did not have time to finish.  The truck is not finished and it's a bit too dark.  Still, I am thrilled with the shape of the truck so far.

I started practicing with different brushes on a scrap piece of paper to see which one to use when it's time to paint "TOYOTA" on the truck.

Again, it's weird, but the picture of the painting looks better than the painting. Why??
