Re: Walkabout templates
On this specific issue, I started with my own style from the CUSTOM graphic editor, and it was terrible and ugly. Next I ripped some walkabouts from Final Fantasy IV, and they looked awesome, but I have a bit of a beef with the practice of graphic and musical rips. After that, I tried my own style again, trying to imitate the old Final Fantasy sprites at the same time. Lately I've also been imitating the style of Fire Emblem's walkabouts, especially when it comes to animation.
I'd love to post some before and after pics, but I don't have any record of my oldest game projects. So I'll jump immediately to the results, which I'm content with. With one exception, I'm going to use fewer shades per color. You only really need two, a light and a dark, unless that color is depicting something shiny or important.


Anyway, to answer your question, it's been a learn-as-I-go process. Practice makes perfect and all that. I've read several tutorials and guides, but none of them made a huge impact on how I did things. Don't get the wrong idea, tutorials are great and you can always stand to learn something, but just reading one, no matter how well it was made, is not going to transform you into a good pixel artist.
So... experience. Get some experience. Make some sprites. Jump into things and get going. We'll throw peanuts at you when you screw up, but those peanuts might have little paper fortunes inside to help you along.
