Quoting Clever Crowe
Like the taller bipeds you've got here. If it matters, Andros; using the black background makes it easier to see your posed shots. Just a suggestion. Cheers!
Yeah... the difference is using the old or new uploader, I didn't actually choose either. I think in future, particularly for lighter coloured designs, I may start adding a background using GIMP to show them off better. It was suggested on Cuusoo that was a better way to show off LDD designs, but I've never tried it because, a. I've never really thought the PNG files looked that bad, b. I'm lazy and it seemed like a lot of work.
