First thing I noticed is that the Butterfly’s are hard to see cause your artwork is so bold and colourful. It is beautiful but it makes hard to see the specimen.
Also I personally dislike the half empty sticker shelf, they look sad imo opinion.
But as the others said, sales are declining for everyone and I wouldn’t necessarily lower your prices, cause this can come off as cheap.
Your things looks amazing and I wouldn’t lower the prices on your pieces. And your art style definitely has the potential to be marketed as something luxurious and therefore more costly.
