>>6130329You should probably read the guide in OP post. But you proooobably wanna paint before assembling for stuff like this. When they're separate pieces, it'll be easier to get into the nooks and crannies without hitting other stuff with your brush.
Also, don't use enamels. I would probably use Citadel or Vallejo paints. Remember to thin them appropriately and not paint straight out of the pot. And since you're new to this, I would probably go for a wash technique like people do on miniatures. Paint all these up in simple flat colors (ie, Chico's shirt with be yellow, his hair brown, his skin tan). Then just give the entire figure a brushover with a wash (or a very very thinned paint). It will seep into the cracks, make the details pop, etc. This skeleton is a bit of an extreme example but you get my point. Do some further reading on this in the guide in OP post and by googling "miniature wash technique."
