Next step is highlighting, washing and drybrushing. So I'm gonna do some youtube research to see in what order and how I should do it to get the best results.
There isn't really a hard and fast answer to that. Sometimes you wash after you highlight or drybrush, other times you do that afterwards. Depends what effect you are after and how thngs have turned out so far.
Washes can be done with either inks, thinned paint or the GW washes you have brought. Be aware most washes are to add colour, while the Black ink wash I detail is more to add shade. Steve Buddle observes GW washes seem to work better if applied in two coats, and that the two coats needn't be the same colour.
Glazing is another technique to be aware of. This is done with a thin, transparent mix of paint or ink but tend to be applied to the highpoints rather than the recesses, like a wash. Glazing with thinned elf flesh is a good way to highlight flesh, but be aware you can do it with other colours.
Experiment with a mix of green and yellow rather than green/white for highlighting the skin of goblins and orcs.
