Geeta you are doing well for using a new medium so keep on "grappling".
Your stones are beautifully painted - or as Charlie said, "suggested". However, as Michele mentioned you have an awful lot of activity going on in this piece and I'd like to see some places less active as well. I also have a question about one area: what is the green horizontal object seen here:
It appears to be something architectural, that is attached to both the tree and the distant house chimney. You might want to decide if it needs to be there.
I'm also wondering if the tree branches against the sky are a wee bit too light and warm in hue.
