putting the pain in painting

Naturally, I am sketching all the time, but I don't get to paint as much as I'd like. I did get to do a little recently- I have an acrylic landscape of a desert mesa beneath menacing dark clouds, but I don't have a pic or scan to show.
I also did this watercolor a few days ago of a morning glory that my sister has in a pot on our deck.
For some reason I like to play with the painting after it's scanned, see what it would be like if i had painted it differently, say, in sepia tones...


or with super-saturated hues...


ah, well, must go to sleep now, I'm bushed after working 13 hours today.
