Looking for some advice to improve myself

Was just wondering if anyone was willing to add me in game that can explain to me what i should be looking for when i watch my recorded games and the reasoning behind it. im def trying to improve and i do very good in alot of games but when im watching my games i dont really know what im looking for to improve on. i know im in bronze 3 right now but i was silver 2 last season so im pretty sure i can get back there easily but i would like to hit gold this season or maybe even plat. im also an older gamer and have 3 kids so im not able to put forth a ton of time to improve so any advice would be greatly appreciated
