I dont do mutch of sci fi stuff so its all good practice, and as for the picture it probably lack a good focal point and alot of other stuff that im not super happy with, but maybe I will get better at it..
I honestly can't see how something this amazing is even possible to create through Photoshop, or to create in.. general. It's absolutely magnificent, one of a kind. The colors and the lighting are outstanding, nothing looks to be out of place at all. You missed NO detail in this whatsoever. I hope one day I'll be able to design and create stuff as amazing as this. Keep up the great work !! I really enjoy looking through your gallery(=
Thats pretty amazing! Don't feel too bad about not having a focal point because it is still somewhat present. The eye is drawn to the center of the image where there is that platform with a circular pattern on it. It gives some sort of anchor to the painting. Good job!
