I still need to learn a lot, I'm far from people that I call pro

I use as much airbrush as I can , because it saves a lot of time, and can give you smooth shading. In this model firstly I've painted whole skin using airbrush with red+black, then added more , red and more, and then white etc. Then I washed whole model with watered "carroburg crimson" by
GW and added some carmine red vallejo ink . After that I used black paint with dose of water to do the black endings of legs and horns and also to make more dark the areas with "dots" like back or shoulders. Next I take normal brush and higlight skin using red, orange and yellow. Metal parts, tongue, nails, dots on back etc were made with normal brush. At the end I made sword using airbrush. First dark blue, then ble and them, more and more white paint, till clear white ( all with airbrush). FInally some edges with brush and white paint, and darker pards of sword with blue wash and brush. Thats all I think. Using airbrush is quite helpfull if you know how to use it.
