Never apologise!
I'd really like to help but I couldn't make a sketch as good as that with pencil and paper, let alone a computer.
Woo Sirrah!

It's not a sketch, it's a sketch effect
I've found the sobel edges from a photo, auto-equalised the colour, desaturated it, sorted out the curves a bit, bit of layer masking, bitta this, bitta that.
