Ninja on Wheels

Now that it's finished, I feel like I've drawn pictures similar to this several times (casual clothes with ghost-like alter-ego in the back). I can remember one with Pulse and one with Raven.

..but I guess if you've drawn enough pictures there will be a few that seem similar. I guess that means I should plan for a crazy-unusual picture in the future.

Edit:

GAH! They're all even the same pose! Although I wonder if anyone would have noticed if I hadn't mentioned it.
