New Tristana build?

Okay so I used my main champion and I tried a rather off meta build that I theorized as I went ahead with it. It allows to be more of a tank buster since in my experience is her only problem or down fall. Most tanks build armor and Health which is really hard for to melt down those types of enemies. So I tried out this build shown below to help with that downfall. The link from replay.gg is my game if you feel like watching it to observe it. Is there any improvements I can make? Tell me please and we can craft a new build together :) or So I didn't get to finish my build in the game just for the heads up. Thanks for helping if you replied. ^^
