want to try new acrylic paints, advice?

Not having much money, I'd probably split that paint renewal shopping into two orders.

For testing the paints I'd probably buy some of their triad sets (most likely the Mid-Blue and the Yellow Triad, as that would mean I'd also have some green paint without having to buy some and the Dark Red Triad) plus probably 115 - Tanned Flesh + 214 - Suntanned Flesh as those look like they'd be good as base colour + highlight.

Not sure if that helps you, but that's what I'd do. That way you'd get quite a few paints to test, the investment is not that big all at once.

I forgot about the triad stuff, thanks for the reminder.
