It looks like it could be a scene in a Tinkerbell movie! I love those movies. LOLI can't really give any tips and tricks about Daz ( I use poser), but for 3d in general.. what I tell everyone, practice and experiementing is how I learned. Take your time building a scene and playing with lights. Try different settings, test render, repeat until you get what you want. Textures are another good thing to play with. The better the textures, the better the picture turns out it seems. Heck look at some of Eve's and Roz and Adi's pictures as examples. I highly recomend VAMP girls and PD textures. 😉
Ummm what else...oh yes, if you see something cool in someone else's picture and you want to know how they did it.. don't be shy and ask them. I'm always willing to try and show someone how I did something. Although I can better help with Poser stuff than I can Daz.
Its half the reason I got Poser.. that and Evey nagging me hehe.
