Thanks for the pdf. Yes, the schematic wasn't usable. The first problem I've found is that SCLK and SDATA are connected to 3v3 and then have resistors in line. I'm pretty sure you had the right idea but made an error on the wiring, but if it's not obvious the resistors should be between 3v3 and the clk/data lines.
You will likely need a pullup resistor on the light sensor., unless the Pi has one internally that can be enabled on analog inputs. They normally just measure voltages and you want to measure resistance. Overall, it's pretty good for a first try !
