In looking again at these designs i wonder whether you could incorporate an "S" "P" and "I" in the actual logo. I can see that possibility especially for entry # 111 where i can already spot an "S" (the yellow winding driveway) and possibly an "I" (the red curve). While I like the design for entry # 111 and the colours are quite vibrant, they somehow remind me of the colours of the Ethiopian flag, so those colour combinations might not work
