Hikari's Dilemma (Newgrounds / Vimeo / Youtube) has been a bit different in terms of how I usually make animations.
Generally, I work from a completed image, cutting it up into the appropriate pieces and repainting any missing parts. With Hikari's Dilemma, I've been using the original comic as storyboards / source material. Because all I have to work with is the black and white comic panels, I have to ink, color, and shade them, converting them to the anime style I want for the animation.
Now, I'm not the greatest artist, but I can, more or less, managing inking, coloring, and with some extreme struggle, shading, of an image that has already been sketched. That's how I've been doing the shots for Hikari's Dilemma. Interestingly, it's much more fun than cutting out and rebuilding an already completed image.
Now, one other thing I wind up doing is making sure that the drawings are on model. I've done some minor modification on some of the previous shots, trying to make things more on model and close to the style from Evangelion. Thus far, it's been a pretty simple task.
But then this shot came up, and I knew I was in for a ride. Here's the original panel:

In context, I know that this is Asuka... but if you were to just show me this image (without the context), and ask me who it was, I wouldn't have a clue. Meaning that I would have to do a fair bit of editing on this to make it recognizable as Asuka.
After a lot of sketching, redrawing, and reference, I finally managed to get something that was looking like Asuka.

A little more refining, and I wound up closer....

I was a tad astounded at how close I got at this point! Then, a bunch of coloring, cutting up parts, and A LOT of staring at the reference I gathered, I finally wound up with something that looked great!

Now, to find out what kind of hell I'm going to put myself through by adding animation to this instead of just sticking to a still...
