Mouse-eared bat skull, part II

And tonight, I give you a mouse-eared bat skull. Sorry I can't be more specific on the sub-species.

Also, this was done using an "new" (for me) app called Procreate. Its brush engine is impressive in terms of realism, but I almost feel that the somewhat digital looking brushes from Sketchbook Pro fit me more. Thoughts?

Anyways, the next in the series will probably be a raven skull. Or a vampire bat skull. I don't think this one is very scary, especially once you see the scale of these little things.

Here's a remake of the bat skull, done with my usual Sketchbook Pro. I'd love comparative feedback from you guys. Any comments on the line quality, is there something you prefer in one of the versions, etc, etc.

Oh, and you should check out the big picture.
