This is one of my favorite WIP. Gradients are very beautiful (9 shades of gray between black and white), this takes time but result is perfect: you dont see that youre using different threads.
There are also parts done with Kreinik "glow-in-the-dark" blending filaments and they are really shining when you switch off the light (my son loves it :))
