AHA!!!!! I FINALLY DID IT!!!
For the longest time I thought that that was an original character.. The one from Screamer's game. Then one day, I was walking around game stop, and out of the corner of my eye, I spotted a game called "Hyperdimension Neptunia mk2". When I saw the character featured on the cover, I thought I had seen a ghost. Then I thought... "Wait... oh he din't.... he-... he did.... THAT'S THE CHARACTER HE USED!".
I had identified the character, step 2 was figuring out if he re-drew the character to put on the cover of his game(because for some reason that mattered to me). Lou and behold, here I have a picture perfect match of what's on his cover..
The final stage is the background... Pinging....
AHA!!!
I WIN!!!!! I KNOW HOW HE DID IT!!! IT WAS PHOTOSHOP!!!!
Step1 Insert Background.
Step2 Cut white parts out of anime girl background.
Step3 Insert Anime girl and position to the bottom left corner.
Step4 Insert Text, and change fill to pinkish magenta.
I WIN!!!! I FIGURED IT OUT!!!!! I'M THE MASTER!!!!!!!
I....I.... Don't... know why I spent my whole evening doing that :/
Huh... That could have probably been time better spent...
Oh well.
