...Yeah, a long time coming, but hopefully it's worth the wait?
I forgot to mention in the tutorial that I use Photoshop CS2. That's the only program I've used extensively, so I don't know if all the information will apply to other programs.
I don't know how helpful this will be, but I gave it my best shot... feel free to tell me if anything seems off or confusing, or if any of my information seems wrong... XD
I don't really know what else to say that I haven't already said in the deviation itself, other than I put an enormous amount of time and effort into this, so I hope it shows.
