I've often found the more I work an acrylic painting, the better it looks. The same can't be said for watercolor, however, and sometimes I brain-fart and think I'm using acrylics and turn a passage into nothing but a puddle of soupy mud.
... which is kind of funny considering my palette begins pretty neutral to begin with. I suppose you could say I turn it into soupier mud than usual.
With watercolors I have to work fast and loose, especially in passages like skies and clouds, or it gets really messy. Brushing out leaves marks on the paper that can't be undone without going over it with opaque paint. I guess it's what professor Ahlstrom at MC was trying to get me to do all that time but I was too dumb to figure it out. Thank you professor Ahlstrom!
My last exam, it turns out, is Tuesday the 15th at 8 AM.
Stay classy, folks.
