Looks like you are having fun and trying different camera angles which for a newcomer I am impressed , great stuff. Lighting will come in time and with how determined you you to learn. The important thing is to kep having fun and don’t put yourself under pressure like some of us newbies do/did.
No there is no pressure for me at this point. I am getting into this because I have wanted to create 3D art and animation for most of my life. I remember experimenting with Poser and Bryce way back when they first came out. I also tried to learn 3Dsmax and then Blender. DAZ by far seems to be the most user (noob) friendly program I have tried.
