I haven't seen your skins yet, but I am certain you are doing a great job. Is it possible for you to post the preview pics instead of download links to the previews? It'll make it easier for everyone to see how your skins look.
At your mediafire account, open the image. It should lead you to a separate page so you can view the image. Right-click the image, and hit "Copy Image address" (or something like that).
Now, when posting, type (opening bracket)IMG(closing bracket)(paste that link)(opening bracket)/IMG(closing bracket)
It should display the image on each post for everyone to see.
Whether you do that or not, keep up the good work.
