Hi,
I have gone through your description that you want created a logo with a fire animation but the project length is only 7 seconds. I will make some small changes to your project. logo will be displayed on the screen during an entire YouTube video
the logo will stay on fire and also some music reaction animation.
I have understood your requirement and I would like to work on this project on the basis on my expertise. I would like to share some of my previous design via chat that I've made, so that you can get the idea of my capability.
Looking forward for your response.
Regard,
Hanan.
