Sometimes you just need to look up. You don't need to be a cloud spotter to love a poetic curl of cirrus or the pillowy expanses of cumulus that float beneath the aircraft's wings as we head off on holiday.
No technique particularly - just look up from time to time until you see something interesting. Decide if you want to include a dark line of horizon or a roof line or just keep it blue and white. I usually add a horizon line to give a sense of place and scale.
Cloud colours intensify as the light fades so sunset is a good time. You can also edit your images to add intensity
