If you want to write more in the new year, another source of poetry writing prompts is "The Music In It", poet Adele Kenny's blog on poetry and poets – the craft and the community. 
She posts a new writing prompt most weeks (usually on Saturdays) and there is an archive for past prompts. Recently, she featured a winter prompt with a series of links to sample winter poems.
