Constructive criticism: It looks better before being colored because your drawing skills are vastly higher than color theory related stuff.
That's not constructive criticism that is your subjective opinion. Further I would suggest you improve your social skills before you start picking fault with other people's work.
I'm not a religious person but this biblical quote springs to mind:
"You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye."
