I have my head in the clouds this week

I am taking an art class as I want to make realistic "things" on canvas and then alter or cover them with abstract paintings on top.
I have not taken an art class since high school - and that was a while ago.  
Last week our teacher showed us a technique for making clouds.
I decided that making clouds on paper was a pain in the behind - so this week I have been trying out making clouds on canvas.
Here is my first attempt.

I am not sure if that is water or land under those funky clouds...

This is a painting I bought for $1 at an estate sale and I thought I could kinda see a landscape in it already - so I decided to cloud the issue.

I painted a light green over the bottom and scratched in some sort of grass like texture.
I thought the under-painting looked kinda fun there under the grass.
I think the clouds came out OK.
I am going to touch one of them up tomorrow.  I wonder what I will learn in class tomorrow...
I can hardly wait...
