it's curious how that details are usually forgotten by the "manip" artists, and they can really ruin the final piece, besides giving a totally no realistic side to it. And most times, we don't know if that is even the main idea, or not. But fortunately, it's not the case!
Yea, one thing that's hard when you do the manip is to really step outside your own eyes/head and think/see as one of your viewers who has no idea what detail work went into it. I've done some details (like eye colors) on some small pictures that I've wondered if anyone's noticed since I've gotten no comments on. It's one of those as an artist you REALLY want in, but the viewer may totally miss it. You just never know sometimes!
nice, search for thoughtful views from others is always one (more) source of inspiration. And it's just great when that happens (as here) and people seem to understand our view. It's not easy but helps a lot to built healthy open minds and even bring new ideas to usual or old things. And the special viewers enjoy those details (probably more) even when we might miss it for some reason but, we really don't forget it because the all style concern is there, and that may be the hidden focus on each work!
