Well I watched your Crazy Lady bus video and your "I Am Alive" video and I've got to say right out of the gate your quick cut edit style is brilliant for this kind of content
it really lets you put across everything you need to say as quick and high energy as possible so big thumbs up there
Couple of little things I noticed just while watching a few of your videos if your looking for constructive criticism:
*I can highly recommend you invest in 1 or 2 cheap panel video lights, your videos are a bit dark and while natural light is fine when your outdoors, inside it can often be a bit patchy and can make things look a bit grainy. You'll probably sink 30-40 quid on some super cheap lights (35-45 if you choose to run them off an extension chord or two) but not only will it really benefit you in giving you some backlighting and highlighting you and making you stand out in your shot but it'll also give you a lot more control over colour correction and saturation
*Also I'd take a look at your framing. while a good close up can make give your audience a sense of intimacy, like they're in on a conversation with you. pulling back slightly and tilting the camera up so you get the full head and shoulders into the shot will again really make you stand out and let you make bigger gestures and give you a bit of an energy boost
*I noticed as well sometimes you use music in your videos and sometimes you dont. I would say use music but only if you know how to sound balance because one of the biggest sins i've encounted with people who vlog (And im guilty of it sometimes too) is either the music is too loud and I cant hear whats going on or the musics too quiet and it might as well not be there.
Other than that the only other thing I noticed really is that your thumbnails are good at drawing people in but i've always been a fan of uniformity...so maybe make a template that keeps things consistent and then add your ideas into it from there
Other than those points (Which admittedly are fairly minor really) Your videos are pretty good, your speak quite naturally and the contents all pretty solid...I would say if your going down the Vlog route to maybe try to do a few regular theme videos like on clothes or hair products or something that would interest you
uploading consistently and using themes sparingly like that should help quite a bit
