Lizard's Fan Characters!!!

I'm one of those people who makes fan characters for everything. -dodges bricks- I made some fan characters for Regular Show, they are sisters/ musicians/ cats.
Character Data:
Name: Del Katt
Age: 21 1/2
Fur color: Red/ white
Other attributes: Wears a purple plaid scarf
Personality: Tough but weird, more mature than her sister and slightly smarter but again, really weird.

Name: Marlo Katt
Age: same as Del (twins)
Fur color: brown/blue
Other attributes: wears a red bowtie
Personality: Immature and cannot drive a car (drives like a crazy) , better social skills than her sister

Do you have a reference so I can draw them sometime? They are awesome
