Mostly I don’t plan paintings beforehand. There are exceptions, but painting for me is primarily about expression.
The unintended similarities between paintings shouldn’t surprise me. They might simply be variations on a theme.
Still, the repetition in the absence of intention strikes me, makes me wonder what is being painted when there is no consciously identified subject.
I’ve called this a seascape, because that’s what the image most closely approximates. I’m also curious about what else it might be.
