From a fan perspective, I rather like it as is, I love webcomics, and this one always manages to hold my interest because I know that every day there's something new. I also follow other webcomics like "Looking For Group" which could put professional comic artists to shame with it's high quality, but the story progresses so much slower than in YAFGC.
The appeal of YAFGC isn't that is has some random one page gag scenes (although they are there), the appeal is that it doesn't NEED the humor to retain it's interest in my opinion, it's story alone wins points on charm and writing. I'd be happy to just be reading this as a pure novel than a webcomic, the story stands on it's own, the imagery is just an added plus in my opinion. Though I'm not trying to undermine the artist's talent, the illustrations are great, and have their own charm, that just like the story, can often stand on their own. It was page one after all, that had no dialogue, that got me hooked on YAFGC.
Not to mention, coming from a similar creative background, most people tend to be perfectionists with their work, and if the creator put as much time and energy into YAFGC putting it out in color, the production would be severely halted, and I'm not sure really worth it.
There's always the adoring fan like myself happy to throw up a few fan colorations every now and then.
best dragon invasion ever!
