Hm, the only thing I can think as a suggestion is going free style for the winter contest. Because, what does winter mean for everyone? Christmas? Having fun in the snow? Spending a cozy time with family? Lying in bed lazy 'cuz holidays? Santa hunting you 'cuz he wants his beard back etc.? Perhaps doing a freestyle contest might give the participant a way to express themselves what they see, consider or like the most about winter? Just a quick thought.
Congratulations to @Belserion for winning the Digimon Banner contest! And @Ustegius as our runner up!
Also, the Winter Art Contestis up! Using @Purity of Magi 's suggestion, it's a winter freestyle contest~ Because it's a seasonal contest, you have three weeks to submit your artwork (deadline is deceomber 29th).
