Agree, it's been edited. Hopefully it now feels a bit less cramped on the top part, not much margin here though and cropping the bottom part makes lose overall balance I think.
Awww but I like squares

Love the sketchy feeling, very well done!

Yeah, nothing bad about it :) I was just wondering. Also in terms of framing, I would suggest to give her a bit more empty space above the head. Atm it feels a bit cramped. Not like it needs to be square, right?

Oohhh I didn't knew about the morse code thing in Panda's piece, that's pretty cool!

Actually I'm not really good at making nice templates or previews in general; here I just started by adding a simple frame outlining the portrait then put the small dots/lines so it wouldn't look too simple or thick.
While I've made 2 study pieces in Panda's style a long time ago, this one piece was not made with that in mind at all. 
Not sure if I should be proud or ashamed that my crappy template skills are bringing up the subject of Panda's art! Haha

Thank you for your kind word and the discovery :)

Very nice. Really like how you treated the outline and shading.

Something I noticed. You are putting little dots and dashes in the corners, I think you started this after your Panda inspired stuff, where he had some as well. But I think you did not realise that what he did was putting his name (NOE) in Morse code into the border. Which is something I have done before and still do sometimes to put my name in in a subtle way. Since the stuff you put in your corners does not make any sense (enp rpe epr pne), I reckon you either missed the morse code thing, or you just thought it looks nice in a way. Was just wondering.
