Thanks for putting this contest together. May I suggest removing the requirement for red and gold colouring though? I know you want to tie it in with the lunar revel, but the lunar New Year is an important event for a variety of cultures whereas red and gold is specifically chinese. For example, origami and kirigami are japanese arts and it should be valid to submit some new-year-themed japanese artwork. However, that would just not work with the red/gold rule, and is an example of how this requirement severely limits creativity rather than promotes it.
Even your example paper-art Annie would not qualify because of the colour. Please remove this limitation!
