The most fun part finished unfortunately and i have a lot of photos. Next step is coloring. I'll use gouache i guess, maybe a little watercolor too.
Here is a photo of my Dexter-like tools.
And here is my filthy hand. After modelling every part i had to wash them in order to obtain a smooth texture and avoid ugly particles on the model. Now i have cardboard textured hands :) Also discovered that touching mouse and camera wasn't the best idea.
