I did pop this on the ‘post your latest drawing’ thread, but I think it can count as my sketch of the day, as I was working on it till the wee hours of this morning.

I’m going to keep adding more and more soldiers until I have a little Sayen Siren army. Perhaps some flying in the back? 
I think I wing it when it comes to composition - or draw really big (or full figures) then crop it all down to fit a panel.
Maybe I should be doing things differently?
What do you do first? Plan and plot, or just draw and make sense of it afterwards?
