Would you mind telling me what you mean by quality? and maybe how i could improve the text?

I think he means, like on the first one. The cropping around the tori is kinda sketchy, also he might mean low quality as in, low res. That looks pretty high res to me but he might have some beast of a monitor or something >.>

Imo, there pictures are nice. Although the text in some doesn't really match the picture, it's good all round. Good job mate.
