Please! Do not apologize. :) Your English is good, it occured to me as I was writing that you might not have Photoshop and it might be pointless for me to write it. Since you wish to know, I'll tell you.

I started with this cap from dbw and cropped it make my base. I crop to 100px x 100px at a resolution of 100px/in. (I don't know how that translates into cm, but essentially I set the resolution a little higher than I will need for the web.)

I did my usual base prep: cropped, copied the layer, sharpened the copy (twice I think because I wanted to highlight the sparkle in her eyes), smoothed the skin on the copy using the smudge tool (5 px, 11%), added a mask to the copy and very carefully deleted the signs of over sharpening. I erased (1 px, pencil, 100%) the sharp white lines at the intersection of light and dark areas that are caused by oversharpening. I erased (~9 px, brush, ~50%) over her hair end eyebrows to get rid of white blotches caused by oversharpening. Probably this isn't necessary is you only sharpen once - or if you know more than I do about the "unsharpen mask." Obviously, I can only do this because it's only 100x100 pixels.

Once I have an image I like, I stamp the image onto a new level (Ctrl+Shift+Alt+E), but you could flatten all the layers if you wanted. I copied twice. The top most layer I set to soft light; the middle one I set to screen. Between the screen layer and the soft light layer, I added a gradient map (foreground = black, background = white) to emphasize detail and set it to multiply. I lowered the opacity until I liked the effect; here it's 38%.

I thought it had too much contrast so I added a dark blue exclusion layer on top of the gradient map(#242b2f) and left it at 100%. That dulls it the colors so I added a gradient map using a brown gradient from the Skin Gradient Pack made by oxoniensis. I used the first one in that set. I set it to soft light and 100%.

That gets me my basic coloring. After that, I worry about lighting. All the next steps are on top of the soft light layer.

I wanted it to appear brighter still so I added gradient #28 from the Art Gradient pack, also by oxoniensis. The gradient is in the middle of row #6 in her preview. It's soft light, 100%, and the gradient itself is linear, 180­­ degrees, so that the darker part falls on the left. Now the colors looked a bit too, "blah" so I added another gradient set to soft light, 100% from the same Art Gradient Package (row #3, gradient #2) also linear, 180 degrees.

That empty left side bothered me so I set my foreground color to black and added yet another gradient. It's linear, set to 0 degrees, and 100% hard light. Great, except it covers up too much of Torri. I clicked on my gradient tool, linear. Make certain to click on the mask for the gradient we just added, then on the picture draw a line from the left side to the right. Magic! No more gradient on Torri's face. It doesn't always work this well, but it did here.

I'm fanatical about keeping detail so on top of all this, I placed one more copy of my improved base, desaturated it, set it to soft light, and then lowered the opacity until I liked it. Here, it's 40%.

One final layer. I chose this pic because I liked Torri's eyes and red shirt. I've lost the red of her shirt so I added a curves layer. I make only the tiniest of changes here because I'm still learning curves. For each separate color (R,G,B), I placed a point in the middle of the line and pulled it up very, very slightly. For the RGB line, I placed points on the lower 1/3 and upper 1/3 of the line and very slightly pulled the lower down and the upper up to increase the contrast just a little.

I'll make a second comment just listing my layers in case that's easier to follow.
