After mucking around with the frame within a frame idea. I remembered a painted I did almost a decade ago, of beach people in outline with a loosely framed sections of a stylized beach (it is about 900 by 900cm square). I still like it and despite a couple of decent offers have not sold it.
So I decided to update the idea of a smaller instargam-ish fashion image (only 20cm by 20cm) and just paint the background of the sky, surf and sand in bright acrylic colours in a beach sand inspired frame. Once I started I released I should also paint the brightly coloured (or not beachwear) but leave the people blank (representing they are only short term summer visitors to the beach). I also wanted strong outline so I found some Indian ink and cut some reed pens.
I like the result (at least this first attempt)
