Don't normally post these, but this one looked like a long bunny descending into some unknown place.
As for the pen used, it was the Majohn A2. Definitely don't get that straight away as it's a plastic copy of their Majohn A1, which is a copy of the Pilot Vanishing Point. If you don't want to draw $100+ dollars, try the Majohn A1 as it's a pretty good copy of the Vanishing Point. Ah, I should mention that it's a retractable fountain pen.
