To me the photos look a little dark?
Is it just my monitor or do other people notice this.
Are you using natural sunlight?
Also, Im noticing some photos are blurring, you may as well just delete blurry photos are they offer no benefit to you in advertising your product to a potential buyer.
Id love to see more vibrant colors.
Also, I sort of thing its hard to determine WHAT im looking at by your first photo.
I do appreciate this photo, if it was clear and bright and maybe at a slightly different angle.
