First Granny Square

I will know where to change colour next time haha, anyways love the granny square pattern that I learnt, you are a great teacher, Emilie! appreciated. :)
I need more practise on controlling the strength of crocheting, the pattern doesn’t look like the same from the teacher however i learnt the technique and feeling great to complete it! 

oh Boy! I made a giant pouch! Is it because i used bigger size (4mm)hook?
