No, that just leaves a bad impression. If he really wanted some advice, he could've easily said it's his first video and ASK for it. Not have his 'friends' backing him up.
You can't expect someone to take that seriously, when he himself didn't do it in the first place.
This is also getting nowhere, so I'd rather we stop, and make a real video next time if you wish for advice. Plenty of people here learnt how to edit by themselves, stop making a drama out of it.
