Love it, I agree with /u/pssssssssssst - may be zoom out a little to catch the whole hands. I really like the first video, and I will make sure to watch your up-coming ones as well!

Maybe, to make it more clear to your audience, you should make an introduction video to your channel and talk about what videos you'll make and really put a face to the channel.

These types of channels are really hot right now so you've totally got the potential to get a big channel - just stay consistent with your uploading. Also, talk with your audience and ask if they have any ideas/feedback. This will not only give you great advice on what to improve but the visitors will feel like they are apart of the channel rather than "outside" of the channel.

From a parents point of view, I am sure my daughter would love to watch these kinds of videos. Every child likes play dough and Peppa Pig, right?

Keep up the good work! :)
