Nice one, looks good, and simple to fabricate.
A small suggestion: Use fishing line (fairly heavy duty coarse line) instead of 'string' as it will stretch over irregularities in the ground, rather than breaking/staying taut, so you can always get that frame horizontal. Dunno if your 'construction line' stretches or not.
I made some frames once with 'legs', again so could always be horizontal without having to use bricks/buckets etc to prop up corners. Essentially a small clamp fixed at each corner holding a vertical steel rod (grid peg) which you can slide up and down til frame is level, glue a mushroom cap on the top end of the peg to avoid complaints from Bovis.
Painting the frame alternately red and white every 100/200mm helps identify where you are in the grid, along with two-tone string (although I don't know f you can get different coloured fishing line).
