More detailed sketches and more common sense

I'm always aware that I need to put down more details in the initial sketch, to make the coloring easier, and to avoid forgetting certain things later. I had always kept that in mind when I'm sketching a character, and completely ignored it for landscape. And now I'm being reminded why a better detailed sketch is important.

My common sense starts to kick in as I lay down the darker shades:

1. Who mows the lawn on these hills? no one. So instead of little grass blades that barely cover a person's ankle, I really should be drawing tall grass instead. Fortunately this was relatively easy to fix.

2. Watch the wind... yeah, the smoke is blown to the right, yet the grass stands tall and still. It's not so easy to fix this mistake now, I guess I'll just have to go with the excuse: wind is stronger on top of the hill.
