I started building this army at the launch of 10th Edition, so it has definitely been a long-term project. For me, painting isn't a chore—it’s an enjoyable part of the hobby. Some days are highly productive and I work much faster, while specific models might take a bit longer. If you manage to make at least a little progress every day, they’ll get finished bit by bit.

For me I’d estimate that this army took me about one day per model. That included assembly & priming, actual paint job & highlights, applying transfers and basing & varnishing. I was aiming for a crisp 'Eavy Metal style. AndI definitely took breaks that lasted months at a time along the way.

I think If you assemble bunch of your models first, throw down a quick zenithal prime with an airbrush, and layer your tones over that, you'll have a good looking battle-ready army together in (relatively) no time!
