Hollala... In this age, it could be, Severus looks like your amazing picture... I was zapping through some sites, and then: Uuuuups, Moment please! Wow, how long have you worked on it? (My english is very, very miserable, sorry...)
This is an absolutely amazing drawing! I am completely shocked that you actually drew a Young Severus that still looks like SNAPE!!! All of the pics that claim to be "young Severus" always end up looking like someone completely different! Amazing work!
Did you use a pic of young Rickman as ref? Becoz it looks greatly similar to one I saw...it would be a coincidence if you didn't I can't say that I like the placement of the ponytail at the side becoz it really reminds me of those young girls with the two ponytails at each side... Probably it was what inspired the "drag queen" comment by nathalsa below Perhaps a little more towards the back.
