He's probably reading Ron's paper and thinking about how it was clearly written by Hermione. This amazing and totally how I would picture Snape if it weren't for the fact I can only think of Alan Rickman when I think of Snape.
Oh my gods, I faved this a while back and meant to comment it, but sooo forgot to! *I blame old age* lol
Anywho...I love this! Reminds me of myself when I'm sat at my desk, surrounded by parchment and quills(make both my own parchment/quills)ready to write! I'm a die-hard Lucius Malfoy fangirl, but I also love Snape! Well done!
Well, this is an old work and maybe you do not want hear anything about it anymore, but I just have to say now when I found this again. (At least I have myself quite weird relationships to my own old pics. )
This express Snape's personality so well. You can really see how he is very tired, but doesn't mind so much about sleeping and feeling well, so he stays awake. He maybe hates the physical part of studying, but still he is enjoying of staying awake the whole night by studying new things. Maybe becouse he can also be alone.
Of course he is very canon too and I like the background - especially the perchaments and texts in there. About the (tiny) bad things I am not going to mention becouse of the age of this pic, but really there isn't many of them.
One year exactly...Wow. Actually I avoid looking at old pics - because when I do, I see how weird and bad it can be and I want to paint over it at once etc. It's quite painful indeed.
Though, some old pics surprised me sometimes - I am, you know - 'oooh, really, is this a pic of mine' ? I even don't remember how I managed to do it haha ( I very quickly forget about the brushes textures, etc etc)...
And yes - Severus is like me here - insomniac ....'Good nights' we have
It looks like he has finished grading papers and is now doing some research of his own. Maybe preparing tomorrow's lecture? Poor thing, he needs someone to tell him when it's bedtime! And some more light, he'll ruin his eyes! (I sound like grandma!)
