then, the models do the pose, but it is almost impossible to maintain in the pose right, because there is not much balance, then photoshop helps correct for example the foot (the real is all firmly on the ground) and other small details
I always loved the original artwork, and you made a work that can fit this feeling. All the details ar perfect, the faces position, the wings, the feet, well, everything is very good. Just a question...you used the model's in this position, or you used parts of different images to build the final one? Embraces man, and keep working!
