Painting from tiny anime figurine

I’m working on this anime figure namely Retsu.. something I forget, a character from Japanese animation called Bleach.

It’s very fun to paint but also very challenging especially for getting the small facial details since I just cannot see them from my viewpoint(where I’m standing looking at it). So what I’m doing is stepping close up to the figurine to observe the details. I have to be kind of be quick  about it to keep the detail I saw in memory and mark that in before the memory fades. I wouldn’t have to rely as much on such memory -painting if I was just painting as how I see it at viewpoint or able to do side by side comparison, but the more hassle/movements there are between the observation and making the mark, the more I‘d need to use the memory-painting (as I like to call it) approach. Also I often like to keep the easel very far away from viewpoint to look at the painting from a distance, which then I’d also need to use a lot of the memory-painting approach. Very exaggerated explanation of this approach would be if you saw a face of a person, a stranger for the first time, in a room ,then immediately go to next another room ,then look at another stranger person, what makes them different and what changes would you make to the second person‘s face to alter and make him look like the first person ? You’d make maybe one little change that you could remember then go look at the first person again then second person then repeat and make the changes little by little doing best you can to try and remember during traveling between the rooms. 

I‘be painted in the details using little dots. Since the painting is very smalll scale, I need to use the point of  tiny brush and apply literally dots as each mark. Kind of like pen and ink stipple drawings. Also very much like how sculptor would apply little pebbles of clay  when doing the details. I try not to think of it as painting with brush because if I think about brushwork I feel that it can become superficial , so I just think of it more as sculptor or building something, instead of trying to do a brushy painting. But this is just me , not that anything is wrong with brushy kind of paintings. Especially if working from life thinking sculpturally and not from photos or something, this non-brushy little pebble approach is ok and still leaves a lot of room for self interpretation /expression since it’s impossible to just copy all you see from life
