Guilt Follows

At first I was very happy with how Snape turned out here, but after some time I think, ugh, that's a bit too fangirlish... =S But oh well... I'll try to keep that in mind so it won't happen again.
I did most of this on my old computer and just finished it on the new one - looked much better on the old one with the smaller screen and strange colours. xD
Anyway, I also wanted to draw an actual background for once and not just make everything black (though I really like the dreary, simple ones) but I don't know if that really works for me...
So, it's about guilt following Snape everywhere - omnipresent and he can't get rid of it. I think that's how he feels, always bugged by horrible memories and unable to forget...

Edit: One thing I forgot to mention: on the right --> Lily.
And now that I said it in the comments already: there's this oddly shaped cloud above Sev's head; it's supposed to be the disguised sword of Damocles - the bad things from his past, ready to crush him any minute; I think that can make one got insane - never knowing when the inevitable will eventually happen.
