Harley Quinn

It's been a while since I'v been on dA and I know I've promised to do at least few artworks with my new art supplies but I guess school work kept me busy as I don't have the time to do so. So I managed to do a sketch of Harley Quinn based on Batman Arkham Knight. Hope you guys like it. I know I still need to improve and I think I've improved my skills a little bit than my last entry here. I'd like to dedicate this sketch to my love. She's really love the character and so I decided to spend my time drawing this for her. 

Overall time taken is roughly 3 hours++
Do comment as it may become constructive for me to improve what I lack. Tips would help as well. 

PS: I tried out some lineart cleaning tutorial for scanned sketch and I think it turned out well. I think? lol.
Oh if you're wondering why the different watermark. Yes, I've changed my alias. I will change my username here on dA as soon as I get my hands on the premium membership.
