I don't mean to sound like a dick, but based off of your initial postings/general view you've presented, you're not going to "make it big" for lack of a better term as an online reviewer. This is of course not a bad thing, many people underestimate professional online reviewing, it isn't just a simple matter of setting up a webcam and recording yourself talking and then rolling in the dough. If you google around for some Q&A by any of the more well known web reviewers, usually the question gets brought up and said reviewers go into great detail about the process. One of the red flags right off the bat was time constraints, if you struggle to get one day to yourself it will be insanely hard to maintain a schedule to create/research/edit/upload quality content.
Now, negativity out of the way this doesn't mean that you shouldn't upload content, but just do it in a more relaxed manner. Throw on a webcam and ramble off about whatever game stuff interests you and toss it up on youtube. If you have fun doing it, awesome, you have a new hobby, if it isn't fun or you get bored after one or two videos then eh, stop. I really don't know why you want to do it though, your initial post really made it seem more like a pride thing or a professional thing more then anything else. To be blunt though, even doing it as a hobby might backfire because, again based on the information you presented here, it seems like you wouldn't really be able to handle any negative comments aimed at you, and well, the youtube audience isn't generally very kind (or coherent) when they disagree with something.
More or less the same applies to your art, do it for yourself because you enjoy it. Unless you're trying to make a career out of it, it shouldn't matter what other people think about your art. One of my friends is actually a pretty decent artist, with another of my friends actually being a professional artist. After seeing the stuff from my first friend I made the offer of asking around and seeing if I could potentially get them an art related job, but they immediately declined saying that it was just something they did for themselves because it made them happy, and how doing professional art would take away the freedom, instead of it being about their drawings it'd be about having to appeal to what someone else wants/considers to be art. If you are interested in pursuing it professionally though, there are plenty of classes you can take, but from my understanding it can be a hard field to break into and if time is already an issue it isn't something I would recommend. The above mentioned friend who does actually work as an artist more often then not also has a completely unrelated art job on the side while waiting inbetween commissions, and sometimes the wait can be incredibly long, and not to mention when he does get paid it isn't exactly enough to outright live off of.

R- Do it as a hobby/for fun, but don't try and turn it into a professional thing.
