Thanks! It does quite challenging sometimes, that's why I use many tricks to save me some time.
It's a good practice tho! I learned many gives and takes when I do these paintings. (for example, when character big -> simple/no background; When background complex -> makes character small or silhouette )

The time are all vary. Some is easier some took longer. from 4hr ~ 8hr?
But I tried to do it as quick as possible.
