All you need in digital arts is just a good software tool, patience and bit of creativity. For instance, the profile picture of this blog post is just a simple composition of a repeating circle created in Adobe Illustrator CC.
Just like in life, complexity is in the end just a hidden simplicity. So, nothing to worry about… 😃🏝
