Matty well done you -great achievement for a young coach .
Advice - I can write a novel on it (being a recent failed candidate of the level 3 -

-however it was a great experince for me and a massive step for me to actually cross the white line and deliver so to to speak )
First up KNOW your topic inside out upside down back to front .
Big one this one -IS IT GAME REALISTIC ??-your set up and start points .
Be organised and control your session and your players -dont be worried about managing the opposition -you cannot coach them as such but if you want the oppo defence to keep a high line and they are not -make sure they do .Players get lazy and can muck you about -so stay strong with them .
Attacking topic -get the goal quickly or shot on goal then your players buy into it -yep this is good I can see this .
coach what you see -me I MISSED a -fantastic cresent shaped run striker just about to spin and turn -midfielder had the ball -and I go stop stand still
I just did not see the run my focus was on the ball and around it -never saw the players movement away from the ball until I interupted it and yep I cringed - and I just went to the young lad "I am so sorry that was a great run "
so I lost my focus for a minute or so .....
So stay focused -and only coach your topic -nothing else .
and GOOD LUCK
take your passion ,and make it happen .
