Loosening up

I need to do exercises aimed at loosening up - my Flickr gallery shows me that my paintings are all too tight and hard-edged. I was beginning to address that in my paint-overs of some of my older pieces where I concentrated on composition and soft edges. Just gotta keep going that way and start doing some new pieces with it in mind. I went through a too-tight phase in drawing decades ago, and I got over it.
