Not at all. Exactly the right direction. Can't you see that the image you want to put her into has a lot of distinction to all the edges? That's the "cartoon" look you were talking about.
Yes, changed the colours. But that's not necessary with yours, is it? Your subject already has the warm tones you'd expect when being lit by that lamp.
I urge you to take it down aggressively first, eg -20, then very slowly bring it back up, and stop where you think it looks most plausible. I think you'll stop lower than -6, to be honest.
There are a few different styles there. The piper one definitely is cartoon, but I'm not sure if that's what you actually want?
Generally this is done with high pass filters. How is this?
Excellent. Now add a Hue/Saturation layer above the boy layer, and clip it to the boy layer (Cmd Opt G). Then lower the Lightness slider just a little - I feel he's a tiny bit too bright for the photo just now.
Can you please send me the exact jpeg file you sent to the lab for printing?

Can you elaborate on this? You must NEVER sharpen during editing. Sharpening must only happen on the output file, after flattening and cropping/resizing.
