Sorry.. but i think too mutch work for an very bad result!
I don´t thnink, that i´m one of the "pro-Painters", but that... my little Brother can do without lesser work / Steps.
As i start to read your guide i was impressed... 1. Basecoat with the Basecolors... thank ink to get shadows... hmm.. why not ... but as i saw the detail picture i get upset... Why so mutch work?
For this result, you might start it mutch easyer and faster... simple basecoat black, and Drybrush all wanted colors! Finaly you might get a better result in lesser time, includet close to no dry time!
