A few tips to help you out, since you're new here ...
Try not to push your items in other threads ... it's considered rude!
Sell your items in the "For Sale" forum rather than the other forums ... multiple threads create clutter and can cause confusion. What would happen, for example, if you listed the same blank or burl in two or more locations and had multiple confirmed buyers for the exact same item??? (Side note, this particular snafu can actually get your ebay or amazon accounts BANNED if you do it enough.)
Use better lighting ... take your pictures outside on a sunny day, for best effect. Those pictures came out very dark, it's hard to see any detail at all other than they are roughly pen blank sized and they look a dark reddish color.
Mist the blanks with a little water, if they are fresh cut and still have a lot of water content. Otherwise, (if they are dry) try wiping them with a bit of mineral spirits, so that you can see the grain in the wood. You can also try taking pictures of them "dry" and "wet".
edit- If you have the equipment to turn them yourself or you can get someone to turn a few blanks at least round, with a high grade sandpaper and minimal finishing/polishing to show off what a finished pen barrel would look like, include pictures of that as well ... discerning buyers like to know what they'll be getting inside those blanks!
