Although I managed to avoid getting too fiddly, the brushwork could be broader and that would, I think, have improved the sense atmosphere further. I've written elsewhere that I feel my work has a heavy and sombre feel and I think trying to introducing some bravura brushwork may help with that. Working with a limited palette may be a factor too, but I don't think that's the overriding reason.
At the time of writing it has been some time since I did a cast painting but I am currently working on a small painting of a skull. I've been trying to work in a broader way on that piece and will post the results here once it is finished.
