improving me play

https://www.dotabuff.com/matches/1387744210

First time asking this question, but i do want to improve, sry if this is the wrong place to do so.

I was the captain here, and played cm. Honestly, i think we got a pretty good draft. But there is probably still places to improve. If there is anything i can improve on, please tell me.

In gameplay wise, we lost first blood tp a lvl 1 smoke gank while getting thw the bounty runes, but we did get both so it was ok i guess?

So, they went for an offensive trilane which i completely did not expect, if i didn't ask for a trilane we would have lost early game. Originally i wanted void to be in the safelane, but void wanted a solo top, so we decided to let silencer safelane. It ended up being worth every bit because axe and sven went super aggressive early game, and fed silencer lots of kill. There was one fight which i missed due to farming in the jungle for a minute, and silencer ended up dying there, but he came back and got a double kill so lol.

Around 5 min lion decided to tp top and start a dual lane, i was really confused then, but axe and sven launched a few more attacks on us and got killed a every time. Void was doing ok at top, and viper was doing well, but i fed a couple of kills while trying to ward.

The mid game was full of us dominating, and void getting fatter until lion and sven shut him down, and silencer died to lion feeding a gazillion xp and gold(lucky it was just lion, but still)

After that, we pushed hard, and got 2 rax, and got cocky and fed sven a rampage(that was stupid.

There are probably other details, which i dont remember as clearly, but please help me point out any mistakes i made, including the drafting period.

And sorry for the bad english
