I find that apart from the Wind Waker version of Link I essentially draw him as the same character no matter which game I'm depicting him from. I'll try to make a conscious effort from hereon in to have a bit more of the various versions' individuality show through.
I'd like to try drawing some more obscure Nintendo characters too but at the moment I'm playing so much Twilight Princess that most of my output's related to Zelda!

Enjoy!
