Supergirl #20 was his last issue even though he has several more covers in the chute. I have had my issues with the New 52 Supergirl, from the decompressed early issues to the 'disaffected' publicity.
But if there was one thing that I never had a problem with it was Mahmud Asrar's artwork on the title. It was slick, stylish, and fantastic. His style seemed so well suited for Supergirl. He drew her like a teenage girl. He had a tremendous ability for facial expressions to add emotion to a script. And he was able to show joy in her despite the book being darker than expected. Even the commission above, used in his farewell post, shows that.
He doesn't come right out and say exactly why he left the book but for his career and life he needed to move away from the book. Everything I have read by Asrar, he loved being on the book. I can remember a Twitter thread when he wanted to know who had drawn Supergirl the longest, as if he was wondering he could reach that plateau.
And on Twitter, Asrar felt he needed to say in very measured words that it was not his health that made him leave. It was something else.
I may be placing my own conspiracy theories on this tweet, but it sounds like he had some issues with DC Comics and wanted to take the high road.
I say this because we know it isn't comics that he is walking away from. Heck CBR just announced that Asrar is drawing the Indestructible Hulk Annual, coming out soon here.
It has to be something specific to DC.
I suppose I shouldn't be surprised.
I don't want to lose sight of the reason for this post. I come not to bury Asrar but to praise him. He will always hold a place of importance for Supergirl and her fans. He was a shining new star for DC Comics who is moving across the aisle to the competition.
I will miss his tremendous art on this book. I can only hope that at some point in the future we see more Supergirl by him.
