Getting an outside perspective on your portfolio can vastly improve your work. By seeking out the opinion of someone in the industry, you can get a fresh pair of eyes on your work and they can often see what you can’t.
Getting feedback early and often means we can discover potential problems with the work early, before we’ve poured too much time and energy into it. We can change course quickly and easily if we need to.
Before committing to making a whole portfolio of work in a new style, test it out. Making 20 illustrations takes a long time, but you could make 2 or 3 relatively quickly. Share them with the world and ask for honest opinions and feedback, see what kind of comments you get and adjust your course for the next set. If you repeat this process for five months, at the end of it, you’ll be a lot more confident that your style is something the market wants to pay for – It’s been validated by multiple people and you’ve refined it into its best form. It takes effort to do it this way and to find people willing to offer their help, but you’ll learn faster, find out what your audience responds to and have a better portfolio as a result.
