they are both in my gallery, guess others (mod) don't think the same as you and I oh well
Chin up, lass! I, for one, thought they were the mutts nuts, but I'm not a moderator and I have no idea what criteria wallpapers have to satisfy for them to be accepted. What programs do you have for working with? If you don't have Photoshop, you could download Gimp which is free LINKAGE. Then just break out the google-fu and search for Gimp tutorials (same goes for Photoshop if you have it). That's all I've ever done. Well, that and dicking around with layer effect settings. Then take what you learn from tutorials and start playing around to see what you can come up with. It can be a long haul, but you will get better as time goes on. And if you're interested, Daz 3D have extended their program giveaway LINKAGE. Just set up an account, and download those suckahs for free. You don't have to install or use them straight away (slap them on a DVD if you want to save some space), but they're good to have. I've already had to use Daz Studio just to create a model because all the nude model images I looked at on DeviantArt were either trying too hard to be erotic or really damn scary, or both.
Keep going, girl. We're here for support and any help you need.
