Reddit mentions of Mastering Digital Printing (Miscellaneous)

Ok, a few things: first, since you're taking your work into photoshop you are going to need to make quality archival digital prints if you plan to sell them to the public. A friend may not care, but it's part of the promise of acting like a professional. I'll admit, I am just learning this process myself, so I'll just recommend the book I'm working with: Mastering Digital Printing. Second, it is easy enough to get stuck in photoshop using only high saturated and bright colors which kind of clashes with your lovely watercolor backgrounds and makes the work less sophisticated. I've been looking for a great link to explain color theory and still haven't found it, but this will at least show you what I'm talking about. Look at the Figure 10 value/saturation scale. Otherwise, yeah, go for it, but don't let it stop you from continuing to evolve.
