Thanks for such a useful and clear list.
This piece is a personal project. I try to document moments from everyday life while learning digital painting.
The mood I want to capture was dad and child enjoying a good book, treasure the time of being together, and captivated by a good story.
Composition & colour: I try to keep the viewer's attention to the child and dad by putting them under a spot light, and apply a distinct warm colour on the child. I also arrange all the toy animals looking back to the story-teller as if they are also captivated by the story.
Medium: I was not very conscious on the choice of medium to enhance the piece. The choice of working digitally, and the choice of brushes were more about trying out a style rather than enhance the subject matter.
As I wrote out my intent, I realised that this piece is not working from the sketch level. The facial expression of dad and the child is not telling the same story as I intended, and the arrange of toys seems unnatural and a bit creepy. I think I need to restart from sketching level.
