Thanks for your comments and advises, Salome. I like constructive criticism, specially if it comes from a great artist as you. I used black pencil to draw the pic and then used a program named Ulead Phptoshop Express 2.0 SE to get the sepia effect.
His Secret Guardian by @frodobolson72 (Artemis)
I like thinking in Snape as a sort of Harry's "guardian angel"(on his particular way,of course). In fact he has saved Harry's life several times...
My, my. Really like the picture. There's still work to be done on facial features because that looks a bit flat, and especially Harry's left shoulder is wrong. It's as if he didn't have any! But more than anything I like the very idea of this. It's got something lasting about it, reminds me much of mythology.
What medium did you use to get that yellowish brownish effect, if you don't mind me asking? :)
P.S. Rate my comment, please. I like helping, and it's only to your advantage anyways. :D
