Your cs counts are incredibly low. Might want to work on that.
Otherwise, good job
The trick is to time the roam, and know exactly how long you can afford to be away from lane. There's only two ADC who can afford to roam often, and it's twitch and mf, solely because twitch has gank potential, and mf has strut to spend less time in travel. Everyone else is too slow or doesn't have a real gank pressure, so they're better off farming while their support roams when the enemy bot/adc is b.
Roaming is a luxury afforded by those who need few items and to a certain degree mobile or gank threat. Adc function more like slightly more mobile, glass cannon turrets; they're stuck in a lane.
