Either digitally or by hand Reproduce a realistic image from a photograph

I have an ordinary photograph (which I will attach to an email to you. I want a very similar or very realistic image of the same photo to be reproduced, either digitally or by, by high quality sketching.
It must appear in such a way that the reproduction is close enough, but at the same time can easily be seen to be a reproduction. They are three different photographs of the same couple seated at the same location but in slightly different poses. I want the reproduction to be big enough so that I can print it out on A3 paper and use it on a blackboard for purposes of education type illustration. Thanks
