Please, in the name of all that is good and decent, give your textures unique names. Even just throw your initials onto it. "Red.jpg" causes problems; if there's more than one textures with that name, Poser can grab the wrong one. "Red_kd.jpg" is less likely to have that problem. I know it sounds minor, but I am really really sick of having to spend half an hour or more on individual products renaming textures so Poser don't throw a hissy and then repointing the files to the new textures. If I have to do that with one your releases, you're going to have to be REALLY good for me to bother with a second purchase.

As Jim (may I call you Jim? I'm not sure what chunk of your SN to grab. ;) ) said, use all three items. You made this totally rocking thing; show it off. Show it from the back! Let me see that it rocks from all angles. If it's a texture set, show the seamlines. You went to a lot of work matching them, let me see that. Show me how your product is different and better than anything else I could buy.

Also, change your focal length. When I see the default Poser "fish-eye" effect --and I can tell it at a glance-- I think "this person does not know the program very well", and I do not buy. The human eye can be approximated by a focal length of 50 to 60, and closeups often look good with something between 70 and 120. Poser's default is a nonsensical 38, which looks distorted because, well, it is distorted.
(BTW, don't build your morphs using Poser's default focal length. I've done this and regretted it; they look warped under a more natural length.)
