I prefer #1 for the same reasons as David
deepop. And the Pastello drops out the text details I like so much.
I like Nicki’s tutorials but I don’t ever learn anything. I spent $10 on a Kindle book on mobile art and not only did I not learn anything, but I disagreed on many points and the whole style of teaching. But I liked most of the author’s results.
Most of my tutorials are app-specific, showing the nuts and bolts of working the app. That comes from my years as a mainframe software developer, writing code and then writing the manuals to explain each screen. Sometimes I branched out and showed the steps that led to a finished work, although that was usually entirely within iColorama, so didn’t include my usual app-hopping. Becoming more specific on a work or style rather than an app means fewer people will learn from it. And there are a lot of books and tutorials that aren’t specific enough on style or apps, and I’m not really sure what anyone learns from them.
