FMP - How am I going to exhibit my work?

Hey guys, I am now at the stage of deciding how I am going to exhibit my work.

Me and my Lecturer was thinking 4 images would work really well together, 2 images of Sophie and 2 of Editiya.

Our Uni group has a group on facebook where we give pear feedback etc and I had some great feedback from another student. 

I have been looking at articles about triptychs and diptychs :

From what I have been reading on the internet, Triptychs are 3 images put together from the same series usually with just a plain border around them, A lot of modern commercial photographers use Triptychs to display there work. 

Could I take my modern version of Film Noir and show it in a more modern way? 

Class mates and My lecturer think it is best to exhibit just three images as they appear a lot more stronger and work better as a series.

I have found some photo frames on amazon for 17,00pound each which will cost me 51.00 pound + 8.00pound delivery to get them on time = 59.00 pound.

The frames are very basic, they just have a basic black border which will work perfect, what do you think?
