Ba-a-ah, the main problematic thing was his pose and it has not changed.
I have a plan for it. sorry my non-art computer (which I was on for a while) is now broken, on my art computer and ready to go :)
Come on, finish this piece! Manupix told the right thing.
Nice colors.
Could improve a bit:
move the guy to the right, between the crane and tree; his upper body and arms say 'run' but legs say 'walk'; right arm is as thick as the legs; lines need cleaning (lots of jaggies); buildings are too evenly spaced.
How about white papers? (not sure)
sorry, will change at once ;) thanks.
