Feedback

I was hoping to feel good about my supposed last layer of the print... (I was going to add one more bug by my head) .instead I feel bad  because of some feedback I got from a professor. She thought that the bugs in the background look like an afterthought, and that the print could be complete without it. To quote: "I look at the bugs and think, Why?" Sadly, I'd already finished all but two prints in the edition at that point, and now I feel as though I have ruined everything. Is it too much? Too little? How can I make a positive change? Now to fix it I must do more work? Should I add more color to the bugs? It wouldn't be so difficult if it wasn't a professor whose opinion I respect.
