I'm not actually picky at all, but the standing Jake McDorman doesn't look nice... OK, here I start:
Can you zoom to the standing guy's face, and make its figure thinner? And move it to the right? Also, I changed his name

Evan Cartwright. Soo... Delete the "a total new Slytherin" either. Just his name. I love the backgroud and the face on left.
That's all

Thankies

[I'll be using it at the new term ;]
