safety wire tips

I agree with FCM4200. Yours looks ok except you should always start the safety wire twist by the hole. The Military standard for safety wire on aircraft is 6-8 twists per inch. I have done safety wire on airplanes for years. You could do a single strand all the way around and have just one twist about 3/4 to 1 " long at the end but double twisting is going to be much stronger.
