I agree with what the others are saying - your videos do look very professional! I love the effects going on in the background, and the cuts and transitions are very smooth. The video and audio quality are both very clear. While this whole video was about low confidence, you seem pretty confident in front of that camera, and like you love what you do! Your personality very much shines through, which is more than can be said for a lot of smaller channels - and this is a great thing because personality is what sets a lot of channels apart from one another, and what makes them stand out. Your sense of humor is great, and there was a lot of great content packed into a short 3-minute video - and these are exactly the kinds of videos I like to see.
Keep up the great work!
