Sometimes it is fun to just look up some reference photo and start drawing. Not trying out any poses or making elaborate sketches… No worries about (in)correct light and shadows… just follow the model!
I made this warrior princess (ink + watercolour) based on a reference picture by AdorkaStock. You can Google her free images (eg. Adorka sword for this one) or follow her on Twitter (https://twitter.com/AdorkaStock). Extensive paid reference image packs can be purchased through several channels (see https://www.adorkastock.com/hub/).
