Solved taking one colour at a time from left to right. The browns were a little tricky, but the colours were fun and easy with plenty of large blocks to make up for the fiddly patterns.
I found this puzzle much less fiddly when I realized that you could do the browns and the green/yellows in one solid colour and then do the pattern over it with the other colour. I did the light brown and the green as the bases and the dark brown and the yellow for the patterns.
