As my only idea for an Art Challenge - "Design a mentioned but not seen Star Trek alien" - was kind of covered with the entries from November's challenge (including my own), I set to scrabbling through the various art threads here, the themes of the previous challenges, and my note/sketchbook for inspiration. And I found it! The December Challenge is: Complete a Star Trek themed piece of art work that you've started but not finished. My note/sketchbook is full of unrealised designs, and I know some of you will have unfinished work from previous challenges judging by some of the comments. Or, if you are one of those people that always finish what you start (your self discipline and time management make me sick! ), perhaps you had some other ideas that you abandoned in favour of your finished art? This is the ideal opportunity to finish something that's been tickling the back of your mind, or full on bugging you, before the end of the year. You can enter 2018 with a clear head - fresh for new challenges! Conditions: You can only finish something that you have not worked on for a month or more. So, if you had an idea for November's challenge, but didn't get around to finishing it, you can't complete it for this challenge. But, any previous months/years are fair game. And your final entry should include the original piece of work as it appeared when it was abandoned, languishing in unfinished purgatory, lost amongst the pressing weight of ideas new... As always, you have until the end of the month - 31st December - to complete your Unfinished Business! Good luck!
