For me, the daily world's nature is in my eye, the imagination is not the finished piece, how the image is lit and composed can make or break the digital art. A beautiful picture can look like crap with poor ingredients and skills. But a slapdash picture can look great if it's created as a painting. The concept is the heart and soul of an illustration, if you don't have that as a foundation, the illustration will not hold up, no matter how it looks.
