Some people will be in disbelief that you did all that in one week but I know it is very doable. I used to crank out ACW by the hundreds - probably the easiest period to paint for me. Yet another back log I've been working on lately. The bugaboo is having time. Always the challenge.
Nice work and enough to have a game already. Part of why I love 15 mm. Paints faster, is less subject to 'quality of paint job' pressure since it is very much a 'gaming' scale (though there are those whose artistry in this size is astounding). Costs less, takes less room to store, and provides for a much larger battle field to play on in the same space. And better figure to ground scale aesthetic. What's not to like!
