Million miniatures challenge progress

I don't have a photo this time, but I've been working on my Cathayan Grand Cannons. The cannons themselves are basically done (they just need varnishing) but I haven't started the crews yet. I was having trouble figuring out what colours to do their tunics (the official art has them in red and blue) but I decided on bone and green to tie them into the rest of the army a bit better. So now I'm at 20 models painted out of the 25 I said I'd do, and we're only just into the third week as of today (Saturday 31 Jan). Plus I've got my Phoenix Guard character at home to finish, which will bring me up to 21 once he's done.

Right now I'm concerned I'm going to burn out extremely hard at some point soon. I have a lot of momentum but I worry it won't last until Saturday 9 May when the challenge ends. 13 weeks is a long time to go.
