I tried to participate in the #艦これ版深夜の真剣お絵描き60分一本勝負 challenge on Twitter, but ended up taking 10+ hours on this piece (time limit is 60 minutes). This was originally meant for the Oct 1st 2017 entry, but I did not finish this until Oct 8th.
So, failing in every requirement of the challenge, I nevertheless still tried to finish this as completely as I could to at least learn/try a few things. It looks like it turned out somewhat halfway decently (at least to my noob eyes).
Looking to improve both on quality and speed going forward!
