Allow me to elaborate

I've been a console Minecraft player for 3 years, but moved to PC around January. Since then I've been grinding both Valorant and Minecraft, but I've noticed that I'm playing Valorant similarly to how I play Minecraft.

I find myself knifing a lot, and getting caught with my knife almost every game. My aim is solid but I find myself using the knife as a sword and trying to place blocks for cover which doesn't work in Valorant particularly well. Since starting a few months ago, I've been hardstuck around Iron. However friends of mine who play in diamond lobbies say that my aim and strategy is a lot better than most gold players.

So leading on, what would you suggest I do to try and improve my game sense and general gameplay?
