Stuck in a Rut?

I'm stuck home today prepping for a colonoscopy, which is a good thing because I have lots of time to think about my latest series and where I'm going with it.  My friend Paula Chung (this months Quilting Arts cover girl) and I are working on a series together involving images from MRI's, xrays and CT scans. Paula's images are more reality based, mine are abstract. The first piece I made is my favorite, and I can't show it to you yet because it may be in an invitational show.  Below is the second piece.

I've noticed a change in my thought patterns as I work through the pieces and I'm not certain why.  I felt like I was getting my groove on with the second and third pieces (below), but now, working on the fifth and sixth pieces I'm feeling a little like I'm stuck in a rut.  I'm trying to recapture the enthusiasm of the first piece, and while I'm still excited about the series, I am feeling a bit repetitive, sort of same old, same old.

So today I'm laying them all out to try to see what my mind is saying I'm missing.  I have felt very pushed artistically by this series and I don't want to let that go. Maybe while I'm under that twilight sleep tomorrow it will come to me.

In the mean time, here's another gratuitous Riley photo.
