Eh, the reason I like doing mismatched eyes is because it mixes it up a little. Makes it look a little more complex. And my shading looks better with mismatched shoes; it eliminates the awkward band of dark in between the legs when the colors are different. Don't worry, there are skins in existence with matching eyes and shoes haha. My very own personal skin has matching green eyes and matching brown boots. I haven't posted it since my computer is screwed, but it exists. :p
And sorry, I don't take requests. Even if I did, I couldn't get the skin to you. Sorry. :c

Thank you! cx

I actually found a tutorial on it in the blog section... some guy named taterman88 came up with it... you ought to search for it, it's a pretty cool deal.
