Her writing looks good enough to be an adult's. The pen control is very good as well, with no smudging and just a couple of misses. The observation of blue for his eyes is very astute.
Mine were certainly worse - one refused to use anything that scratched or squeaked on paper and the other one created 99.8% rainbows. Both were uneven, messy and far, far worse than that at 8.
One had hypermobile joints and really enjoyed using larger scale paper and paints rather than being constricted to standard sizes, the other liked large scale and lots of colour/texture/collage because it felt more natural to use her arms and hands rather than just her fingers.
They were both crap at bike riding compared to the 3 years olds riding one handed and doing stunts around our block of flats, the messier one would always throw herself into things anyhow and end up in a bruised and grazed heap at some point.
Didn't stop either of them getting first in Arts degrees, one in Fine Art, one now lectures in Textiles - and they both had perfectly nice handwriting by 14 and 18.
Pen Licences were for 11 year olds when they were at Primary, though. Saved making 8 year olds feel like crap for not having built up the muscles to write legibly yet.
Do her fingers bend back at the joints as she holds a standard pen?
