I cringed on all of it to be completely honest... but I'll give the OP props, more balls than me, that's a fact.Made me chuckle a little but I found myself cringing after a bit, also you seem to be super uncomfortable during the intro, which I think you need to work on... y'know being more approachable for the viewers and audience.
Also, I'd say take things slow, don't try and force yourself out there and please for the love of god don't try to be someone you're not. You start to realise how stupid that makes people look (fouseytube, sam pepper, ricegum etc)
But there's my two cents, work hard my dude!
