A few key points -
Your titles need more keywords, of the four used in the first listing I looked at (Pretty Bouquets Colours Available), IMO only one is actually relevant and, more importantly, the kind of word people would use to look for products like yours (that is, Bouquets - the rest aren't words people would generally use in a keyword search). You need more relevant words - eg rose, specific colours, other things like material if they're fake, or fresh if that's what they are (I honestly can't tell :8} ).
Having country of origin as China suggest to me they're not fresh flowers, but chances are you'll get someone making assumptions one way or the other, not ask questions to clarify, and you'll wind up with less than positive feedback.
Lastly, you have 'colour: as seen on the picture' in the description but have various colour combinations in the image gallery; that's likely to confuse some people, and many won't bother taking the time to clarify listing details with you, they'll just move on to another listing that leaves nothing to guesswork.
If they're only available in one colour per listing, you should only have one colour shown (and have that colour in the title). If people can choose from a range of colour combinations, you need to make it very clear what colour combos are available, as well as how people can choose and let you know what they've decided upon. It's also a good idea to have a 'default' colour clearly stated - eg, if a colour is not selected by the buyer, xx colour will be sent by default.
I hope that helps.
