Finishing touches are always very important. I added a heart design on the front character's shirt and added musical notes, leaves, and birds flying in the background. I also went over everything and outlined it with a black or light-colored, small brush. It seemed to really pop things out more, especially the clouds (Fig.15 - Fig.19).
The final result can be seen in Fig.20.
I hope you enjoyed the gang; take care and God bless!
