I tried to recreate MSD and clearly I'm not skilled enough for that. But I did find some features that could be improved as it restricted the amount of customisation I wanted on the model.
1) Eyebrows - Would be cool if we could move the height of the inner and outer eyebrows separately and also add the ability to adjust the curve point height. In addition to that, ability to change eyebrow hair thickness, inner/outer length and opacity (denseness) would be awesome.
2) Eyes - *Visually I feel the eyes need to seem more like a sphere in a socket i.e. a visual bulge out of the socket, with double layered eyeball in the middle. Some veins could help the visuals too.* As far as the customisation options are concerned, this is the only other aspect which I feel needs much improvement especially as the look of the eye can make or break the likeness. I guess having to choose from different preset shapes and then using the current customisation options could help a lot. Also addition of eyelashes can give the perfect finishing touch.
3) Nose: Overall size outer limit can be increased.
5) Mouth: Upper and lower lip size inner limits can be decreased.
4) Chin: Chin angle can be added. Chin depth outer limit can be increased.
Other than these I feel I was able to get what I wanted with every other feature. (I'm not mentioning HAIR as Big Ant has already told us that it will be improved upon.) But WOW! that new lighting is amazing, also the skin textures. The models are amazing! Thanks BIG ANT for what you are doing for this cricket community. Keep rocking
