Good effort!!
But it's lacking the attitude and sophistication were looking for.
This is a funk band, with live horns, drums, percussion, with hip hop and electronic influences. The lion has to represent that attitude.
This logo here would be more suited for a business like a bank or something even more formal.
I know it's hard, but the lion needs to represent passion, and needs to have a soul.
It needs to be more of an artistic piece, then a standard logo (similar to the attachments in the creative brief).
You're welcome to give it another try if you would like.
Thanks again!
