Thanks guys!
When I try to shade, what happens is that I can easily see the boundaries between shades.
I was thinking about mixing the purple with very little black or darker purple then use this on the darker areas. For the highlight, use mixed in a little of the original purple (my mix is darker). After doing this, do a blue wash? Will this work? Sorry, not every good with highlights and shading. It\'ll be great if you can help with more detail steps.
I\'ll also work on the eyes. I haven\'t gotten to all the details yet but will drill all the guns later. As for the base, I\'ll do some red ink wash. This should reduce the yellow.
Again, thanks!
