I'm getting warmed up to watercolors again after not using them for quite a while. I do of course still love my colored pencils - but doing this same piece in pencil would have taken twice as long, at least. For my children's book work I want to be able to work faster, so am going back to this medium. Oh, its not fast - just faster than my pencil technique. I actually don't mind spending time lingering over an illustration, not at all. Its just that deadlines require one to move it out of low gear pretty frequently, and with pencils that's kind of not possible. One just has to work longer to get the same result.
I had to get used to, all over again, how watercolors dry differently than how you put them on - they get lighter, and duller (not shiny, like when they're wet). Well I knew that, but after using pencils for so long, where what you put down is what you get, it was an adjustment.
Its like exercising a different part of your 'art brain', using a different medium. And I think that's good.
