This is my first scene ever, also it´s the first project I consider finished.
I would like some feedback.
thanks!
WELCOME!
Although I like it’s concept, it has too much black area, and not enough focus.
The materials are fairly generic, maybe look a bit more into procedural textures, and material settings.
First things really that I notice are 1: No AO (or it’s effects are not showing, because of bad lighting)
2: NOTHING behind it.At all.
3: It is perfectly symmetrical (never good, a scene should have atleast some changes between sides)
4: Bad material settings.
5: It looks like a minature.
Turning on AO increases realism a lot, and gives a more pleasing, less CG image.
Try different perspectives to show less background and more “stuff”. Backgrounds are very important to an image. And this scene lacks a setting. It should be somewhere (whether that be a field, or a rainforest. Up to you) This could also fix point 3.
Material settings are mainly about trying stuff out, but downloading material files, then studying what makes them tick is a great help. But a general rule, turn spec to 0 before doing anything.
The perspective you are using makes it look like a minature. Try lowering the camera. Try to immagine yuorself in the scene, and then ask yourself “Can I fly?”. The camera is too high.
Good luck, hope I didn’t come off as too harsh. I can be a demon.
Well, Wefyb, I would come behind you and say that "it is a good start … a very good start … certainly a good ‘finishing point’ if you want to be done with it … but also a scene that would invite you back to work on it some more if you happen to be so inclined. The perfect symmetry, even the present choice of materials, all of these things are not necessarily bad things if you happen to be shooting to express these qualities “of the goddess in question.” (Goddesses are noted for being very particular about such things, sometimes.)
In fact, I would cautiously step out on a limb and say that I really like this shot. “So far.” (Pardon me, is that my glove there at your feet? Oh my, how did that get there? Would you care to pick it up? 
)
As for me, I’d like to see some exploration of different camera angles. Maybe separate the shot down using a compositing-based approach so that you can start putting “layers” of new things in (and, maybe take them out again) without starting over. I think that there are some really strong notions in this shot which could be pulled-out even more strongly, and, yes, some weaker parts of the current rendering that could be … if you are so inclined … improved.
“If what you have now is a concept-model for, say, The Chronicles of Narnia, and you just got the go-ahead from the artistic director to take this one step forward, what would you do next?” (And how would you plan to do it, knowing that the deadlines are going to start falling faster and faster now that your idea just got … yay! … ulp!!! … “the green light?”)
