I went into 2013 with a lot of goals, one of which was to paint more. I hit January pretty hard and completely my Space Wolves half way through. The Monthly Painting Challenge kept me motivated throughout the year and gave me a short term goal to reach for. I gave each army about 3 months of my time to keep things interesting. Even the table and some of the terrain were completed this year.
My Eldar got the short end of the stick and I only have completed that small batch after I lost some motivation around Thanksgiving and my school workload increased heavily due to a capstone class (another goal of 2013 - Get my Master's degree; which i'm currently 93% completed!). However, I have a whole load of Eldar more than half finished which I will complete before jumping back to Tyranids for their new codex (So excited!)
