I have been producing all types of videos for over 3 years, I think you videos are ok but the audio is poor, invest in a decent mic or use audacity to take out the background noise.
Market the video better, share on all the social media platforms, approach viral blogs and offer to get post for them ... thats a great way to grow. You can guest post to my viral video blog if you wish. Contact me at
