Would you be happy to receive something of this quality if you commissioned an artist? Why? Why not?

I currently have an etsy listing for pet earrings and my husband suggested that I should also make a listing for pet portraits since I’m already doing something adjacent. However, I took a look and that market is soooo saturated right now! There's a lot of great artists there and I'm just not that confident of my work.

I just created the line art today of my own dog to make as a sample for the digital portrait listing, but I really just want some general opinions on if I'm wasting my time and money before I go ahead and colour it.
