Super painting and yes a faint shadow would add the finishing touch.
Yes the advantage is less waste and it’s lightfast so no fading. I had the paint bought as a Christmas box a year ago,it’s vibrant colours too, You can find out about it on YOUTUBE. Search DR PH MARTENS HYDRUS WATERCOLOR hope this helps.
The only thing i'd add is the tiniest and faintest of shadows under the pot, so that the whole thing does not just float in mid air.
