今年のクリスマス絵に始まり
去年のクリスマス絵、他のまとめに含めなかった絵、今月描いた絵の詰め合わせ。
今月連作が無かったのは大体最後の一枚が原因です。

Contains drawings from this and last Christmas, drawings not included in other collections, and drawings from this month.
The reason I didn't draw a series of drawings for this month is because of the final picture
<tn>The final picture is the Factorio one; this post</tn>
