A Cool Cat

I'm using an old drawing of a lion as a base for a cool idea.

I wanted to use think black lines and give the lion a sweet pair of greenish-blue iridescent sunglasses. I've been having so much fun with this idea especially with glitter watercolors I happened to get this past Christmas from my artist friend, which absolutely made his shades come out better than expected.

What do you think? Should I turn this into something more?
