Heh. Heh. Now let's not get too huggin' fruity here. .p
So, you put in the base colors sharp, then locked layer opacity to keep the edges sharp while you worked with soft brushes?
Juust curious; used without photoshop wizardry, soft brushes tend to make a mess of things. .p
Well...that was not the way. Sharpening was done only when the colouring was finished. (and actually didn't changed but about 0,01% the drawing

). The base colouring was done according to that tutorial in DA. It's an amazing tutorial btw, and it explains many of the things i've done. All the painting was done with soft brushes. ( about 15-30 % opacity and flaw) But i used additional shading and lightning according to your way. + i used selection areas according to Epantiras way. Plus i used verious extra personal adds. Well i also used more than two layers for coloring, adding totally 3 tones of colour. But with the shading and the lightening, i used also two more colors. So it ended with 5 different tones. I didn't followed your advise in everything, so instead of making shading with black and white, i choosed similar to black and white colours (which were blending well with the other ones) and painted very carefully some areas. All done in high zoom with carefull work. But if you work with soft brushes, with a simple color-layer you can accomplish more than 4-5 tones of that color. So the real tones maybe are more than 20 on the spider! Believe me it took me many hours.... But i think that it was that, which made the spider look great. All effects were done after the painting. They were actually only usefull for the blending. I didn't use any dodge or burn as the tutorial on DA suggested because when i tried it, it mostly ruined my colors, instead of making a good effect. A great change was done by choosing the right pseudocolors (carefully so that they won't ruin the image) and by using the right contrast. And some lightning & shading effects were added. Well the effects have no meaning if the base painting is messy but you know the right amound of light in the right place can make a good painting great!
