I think it's done - I think it is done!!!
Finally, I think that I can say that it is finished - due to unforeseen events I wasn't able to work much on it last week. The last few days I made up for it though, and to-day's session suddenly seemed to bring all the pieces together to the point where I think, that I can say that "here it is" and this is what I wanted to achieve. It is such a relief after several times feeling that I was almost there --- but not quite yet ----- the feeling that this is OK, but something is still missing ---- I need to do better than this.
I'll sleep on it and hopefully feel the same tomorrow.
And then I'll post a photo of this, my problem child.
