Wouldn't you like to have a cup of tea with this little guy? I'm sure he would love to join you -- two lumps, no cream.
I've been playing with negative space the past two days and I'm really liking the results. I do the original sketch, transfer it to the watercolor paper, lay down a light wash to get general shapes, and then I erase all the sketch lines. I don't like being able to see pencil lines through the paint and this seems to be the perfect solution. It takes a bit more time, but I'm getting a more polished look (in my opinion) than all those messy lines. It may just be because my lines ARE messy and therefore make the finished piece look messy to me. Other artists may be able to create lighter or more tidy sketches, but that is not me.
I hope you will take the time to join Mr. Squirrel in a cup of tea!
