I need help perfecting my gig

Hello there, I have been trying very hard to come up with unique gig ideas, and one seems to get looked at a lot, but hasn't taken off at all.

I wonder if any of you Fiverr veterans could possibly have a look, and perhaps offer advice or suggestions, even point out the negatives...

I would truly appreciate any and all help you may be able to offer to make this gig work for me. Thank you kindly.
