Exactly ... the archetypes do just take over. Not one of my paintings has ended up anything like what I began with. I think that is why they take me so ling to create. I think that Em really nailed it when shie said that you have entered into the Hero aspect of the Fool.
And, this reflects one of the things that I love so much about painting tarot. Somewhere along the line ... in spite of (or maybe because of) reading my way through nearly every volume of Jung's complete works, I have dropped the idea of the Fool's Journey from my deck... that he/she is the hero of the tale told by the Majors. There is absolutely nothing wrong with this approach, but it doesn't work for my deck. Consequently, that alters the way I 'see' the Fool. Mine will be (at least in the 'in-my-head' stage) a pure fool - loco - the naive clumsy clown.
Your enables me to see the heroic in us. And that is a very positive thing ... because I tend to see the other side. We need both. In my mind's eye, I see wings on your Fool, an Icarus figure - who could indeed be seen as the Fool.
I await your transitions with awe.
