Render time will depend on lots of parameter. It will depend on the number of objects, lights, reflections shadows, opacity and..... Last parameter also is you computer here the operating system, processor, memory will also play a role. A simple base figure should not take to much time as DazStudio is very fast in rendering so one or two minutes should be fine also with a slow computer. I made a test and could render the base Victoria in 10 seconds but I have 2 GB memory available and there was nothing else in the scene. I do not know if you will find somebody to buy you the head/body morph for Vicky but you will find lots of useful stuff in the free stuff, Poser, Morph Targets here at renderosity. You also should play with Victoria that is in the base content to download for free with DazStudio. If you select the head you will notice that there are some head morphs already with here. Maybe this will already fits your needs. Have fun with your render and learn as much as you can Jacques
