I'm always amazed at what a fresh perspective can do. Often I'll finish a work of art and think it either looks great or terrible, and the next morning I'll wake up and look at the same work and think just the opposite. I'm sure the art didn't change (although art gremlins sneaking into my computer and altering my illustrations would explain a lot). The illustration above is just such a case.
I'm finishing up the latest issue of Wandering Koala Digest and have everything ready except the cover, and the cover is probably the most important part, because it is what will catch the readers' attention or wave them off and away. The image above is my first attempt. I thought it looked pretty good last night when I went to bed, but this morning it's disappointing. The drawing is nice. The composition works. The colors are unique. But it doesn't seem catchy and inciting enough. Which means I need to come up with a second version. And it also makes me glad I didn't rush out and publish the work without taking a second look at the cover.
I remember in art school how one of my instructors told me he would set up a painting at the end of the room so he'd see it first thing every morning for several days. This allowed him to see the work with fresh eyes and catch things he missed initially but those looking at it later would catch. It's a good technique and practice, although a bit of a luxury in the commercial art world were work is literally being pumped out with tight deadlines.
