Spider-man And The Green Goblin... Didn't We Just Do This?!

Man... What a GOOF!! I had hidden this piece away out of pure embarrassment, but I decided to list it anyway since I have so few Green Goblin pieces in my gallery.
You see, this is one of the most embarrassing things that I have ever done and it pains me to even admit that it ever happened. I was commissioned to do a Spiderman piece depicting Spidey going to battle against the Hobgoblin. Well, I got so caught up in the work and didn't pay attention (too many all nighters)... and thus the Green Goblin was thrown in by mistake!
I like the piece (as much as I can like my own work anyway), so I thought I'd go ahead and list my shame for the world to see.
It's on eBay if anyone is interested by the way. Just don't make (too much) fun of me. Man... what a moron!
