Vision- I love the fact that you uses shades instead of colours and that the shading is almost perfect. And is kid wearing a skirt or?
Orginality- I've seen quite a few of these. But it isn't so common.
Technique- I find that the angles and position is well fit and calibrated,(IS this even tech?)
Impact- Its quite nice to see what they'd look like when they are older. The impact for me is great.
Over all, I think this is amazing. Good job. Sorry if my critique sucks, it's my first. But seriously, very well-done and clean. I bid you good ulck with more of your work. Continue the great work.
