FINISHED!!!
I've used Citadel Shade "Nuln Oil" in place to make an oil wash. I'm fully satisfied with the shade
Easy to use; you just take a fine paintbrush (I used a 3/0 one) and you fill the interpanels lines; using a humid Q-tip to erase when you make mistake (Q-tip to use immediately, shade is drying fast)
Then I used Tamiya "Green" pastel
Finally I glued the little parts and removed the Eduard masks
...And that's it!
Kovozavody Prostejov produced an excellent kit that ask just for a little of work to become a jewel...
For the photos, I placed the kit on a base from Frédéric Mertès.
