Well, I'm more of a techician and builder, than an artist, actually
I showed my pal how I do this stuff and he was amazed having thought I built it all by hand, which thankfully I don't have to or I'd be here all year making 1 scene, lol.
Using Poser takes a lot of the hard work out. getting it looking good though, and other issues, yes, that takes skill...but it's skill
most folk CAN learn, you don't have ot be Rembrandt, just have imagination to imagine a scene, and a lot of effort and patience ot learn the skills.
I'm not a gifted natural artist, I can't paint that kind of stuff, wish I could!! I just imagine scenes, and work out how I can achieve that.
Give it a try, you may like it

You can get DAZ Studio (an alternate version fo Poser, sort of) and "Michael" and "Victoria" stuff free, and Bryce 5.5 is sitll a free legit download on Download.com
I use Vue Infinite to build my scenes in, but it's expensive, the "demo" verison though
iirc, last for ever, just adds a big watermark to pics made with it.
