Wow 
Is he a fan of Bruce Timm (my favourite Harley Quinn artist) by any chance?
Is it time for the dance of joy yet?
Added some colour to it... Hope no one minds... Never mind it's not all that good anyway...
What ever...
Just get it...
Over with all ready...
That looks cool, nice job on the coloring 
Many thanks!
Edit:
Gotta say this have really made my weekend
First the cool freebie sketch from Alex Dai then Kooma coloring it on his own. This has really put a big smile on my lips
Saw over on the US forum he was gonna do 98 sketches to celebrate his grandfather turning 98 year old. So i sent him a message asking if he could add in Sapphic Neko to his list and he said yes
And oh em gee i look fricking awesome!! sexy, cute and totally wicked!
He really captured her, how i visualize her in my head
