1. Nose looks too long:
when compared to Reeve's real life front shot, his nose's length looked a lot shorter than the sculpt. The reason why the sculpt's nose looked long was because the brow bones needed to be laying lower to the nose, as low as where the corneas (of the eyes) were.
2. Looks like a lizard:
I lost other good, more detailed pictures of this particular look, so this is the only one I found that had the weird lizard look. I decided to push the eyebrow bones way down to be in the same level as the corneas (the bones wrapped around the eyeballs at the top all the way down to the nose bridge), it's very much like how the brows look on lizards, which makes it look like it's angry all the time.
3. Proportions looks about right, but head is too big:
I started from scratch all over again. Didn't want Super-Lizard. So, this time, I sculpted the face by looking carefully at the nose and eyebrow bones. Besides the inaccurate facial features, it was the PROPORTIONS of this face's features that looked a lot like Christopher Reeve's, so I was a little excited to see that. Unfortunately, I discovered by measuring the head to Christopher Reeve's head/face template I designed that the proportions and size of the head sculpt's facial features and head shape was NOT in scale for the 1/6th scale figure. This kind of size was only acceptable for a figure that would stand at around 13"-14" inches tall. I don't own a Hot Toys CR Superman, but I'm pretty confident the size of this head sculpt was very similar in size compared to HT's version, because HT's CR head is too big for the Reeve body type, which explains why some fans complained about it, and revert to Erick Sosa's Reeve head sculpt. Erick Sosa's head sculpt had a smaller head shape compared to HT's version.
(really wish Hot Toys produced the prototype version which had the smaller head, because that particular head was MORE in scale with the body, and looked more like the proportions of Reeve's head/body ratio in real life, but the CR head sculpt they produced now actually looks a lot like him, but the head size is WAY off compared to the body, you'd have to buy MOS figure body to have HT's CR head to be more in scale)
4. Features too wide compared to Reeve's:
I decided to sculpt the head a little smaller, and because of that, the eyes looked more wide-set compared to how Reeve's eyes were. I didn't notice this at first. I'll explain why in a moment. Also, the nose and lips were too wide compared to Reeve's. Reeve had VERY narrow nose, and small, thin lips. Because of these small nose and lips that he had, they really made his chin/jawline look bigger!
5. Good proportions and size of features, but my BIGGEST mistake was to ignore the sculpt's wide-set eyes:
So, after I finally made lips and nose smaller in width, the eyes looked more wide-set in comparison. I did notice it, but that's because I've always thought Reeve's eyes were a little bit wide-set in the movies. I just didn't know the sculpt's eyes were TOO wide-set for the face until I painted the entire face after I baked the sculpt.
Because of the eyes being too wide-set, I had to spend almost two weeks now on the eyes to coincide with the rest of the features AND get it to be in scale of 1/6th scale figure. The new CR head sculpt is still under construction, because I want its skin tone to be as smooth as possible, and the shape of its eyelids to be STRONG in clay (previous ones kept cracking into pieces) and be as accurately sculpted as possible.
