Last step, lettering.
I'll post something about font choices at a later time, probably showing a file I use to keep track of my fonts. The main gist of it however is that font choice can 'show' how something sounds.
Example being the more ragged font used for Tails's word bubbles here. I could have used a smoother, cleaner font, but I wanted to get across the idea that the breaths are more 'gasp' like in nature.
