Oh man, Dave, this has become fantastic!!! I totally dig it! The darkening of the leaves is perfect! It brings out the beautiful rendering of the rest of them, which previously has gone nearly unnoticed by me, to be honest. This is fantastic! I'd call it a wrap already, but I wouldn't want to stop you, of course!

It may be a little weird, that the leaves in the top left background feel like they're out of focus and behind the Iguana's head, including their size, while they obviously mean to be in front of him. Claim that it is surrealism ala Matisse and you can call it done, hehe!

To jump on the daily sketches and do a few fast sketches might be a great exercise for you, too, of course! Thanks, jim, for teaching me a new word: divagation! Nice!
