Presenting work for an exhibition

Hi,
I really wanted to pick the brains of industry professionals/post-grads etc.
Im a recent graduate and will be exhibiting my animation and 2D design work at a graduate show in London. Was really interested to find out any tips about presenting 2D digital designs, sketches and screen shots so that they look really professional...should I frame or print onto canvas? I did mount my work onto foamcore for my end of year show, but this looked a bit shoddy in my opinion! does anyone have any ideas or advice?
many thanks ;)
