Thank you sir. I primed the wood panel with acrylic gesso. (You can by gesso'd panels from Blick or Michaels . Speedball makes a good one.

The gesso accepts the watercolor so you paint directly on it. I didn't seal the gesso with anything so the surface wasn't very slippery like yupo. I painted the acrylic layers directly over the watercolor, mostly with a sponge (background trees) and palette knife (ground plane, cliff face, foreground evergreen/) The sky was with a 1 inch flat brush. The acrylic dries so fast and seals as it drys so you don't have to worry about the watercolor pigment rising up and alternating the subsequent layers. You couldnt do this with watercolor and oil for example without permanently fixing the watercolor since the pigments would become suspended in the oil paint and muddy the layers. What is nice about doing the underpainting in watercolor like this is its easy to lift off the pigment to make changes until you come up with a good enough design. Also black watercolor looks a lot like charcoal or graphite (but much less messy and goes on faster with wet washes. ) I did make a change since I uploaded, here's the current version. Alot of pastel painters or oil pastel painters under paint with watercolors. Thanks again!!
