Rock Painting, a new artistic challenge

Recently I started experimenting with painting on rocks. I find this type of painting very addictive.
The challenge is finding rocks with an interesting shape and pulling an image out of it.

These two rocks I collected today while we were fishing at the lake, I saw a bird shape in the rock in the back and a flounder in the one in front.

After I clean and dry the rocks I apply a couple layers of acrylic paint mixed with medium to give the rocks a good base coat.

Here is a blowfish I'm working on now. In the back you can see the rocks with the grey base coat on.

This is what I've done so far, I'm still getting a feel for all the possibilities you can do with rocks.
These I will start listing in my Etsy shop.
The last few weeks I rearranged my selling venues.

I have a new website for my original paintings    http://www.patrick-odriscoll.com

My Etsy shop will have aceo's, and small 5x7 original paintings along with the painted rocks.

Still Life Flowers

Flowers  8x10 oil

I almost forgot about this sketch, I was going through my drying rack and spotted it.
A couple of weeks agoI took some of the flowers out of the vase and laid them on the table to paint..
I used a (gessoed over) panel, which is a painting that didn't make it.
 Luckily I have a box of them to practice with. This was the setup for the afternoon practice session.

I used a limited palette of  cad yellow med, crimson, cobalt and ultramarine blue and white.
