Art & Deco Advise Please

Today I am looking for decorative advice from my world renowned expert panel otherwise known as my blog friends. I am now the proud owner of 7 stunning Proudly South African paintings from the following artists in no particular order:
S. Gornitzka, M. Thomas, H. Mummen, S. de Lange, M. Chaprai & R. Straveh-Levies
I am very proud of the progress in my art buying activities which I started in December only (I'd just lie to mention that between books and art my wardrobe and more importantly shoes have seen no new additions since :( _oh the sacrifices).  The challenge I find is sometimes in the placement of these babies once bought I’m trying to buy keeping in mind what I like and what would look good where and for someone who’s doing this by trial and error but this is is easier said than done albeit it being great fun. I’m am now attempting to tackle a white elephant in my second (wall straight ahead), less used lounge as featured on the left (right to you if you standing behind your computer).

I really just don’t have the money to buy one or two big paintings for it so I'm collecting bits and pieces. With today’s latest acquisition (I didn't write Confessions of this Shopaholic  in error) my son and I were considering various arrangements before we drill. So here they are, please advise what arrangement you think would look most attractive on this wall I am biased towards a one in particular but want your opinion first..
Feel free to make other recommendations.

Without further ado:

Arrangement A

Arrangement B

Arrangement C

And just for the fun of it, let me introduce you to my soon to be art teacher. I suspect she will be both my most favourite person in the world (at least for a time) and the bane of my existence. Oh and apparently stick men, which I thought were the easiest thing to draw require an incredible amount of expertise. So if I come away still unable to draw a stationary stick man, then I'll know Lente is not all she's cracked up to be.

I caught Lente being creative with this Tango peice.....(phen-bloody-nomenal)

I also want to tell you that sooner than later I will finally feature my Art Page (look out for it). I've been dilly dallying on this because until something feels just right I procrastinate but 2 days ago I had my brainwave at last. I will feature the small galleries and framing places I visit and love. This way I can showcase South African talent as a means support for their work and hopefully garner a little exposure for the enterprise. By the way, Lente is one of those artists @ the Colourit Studio. 

Oh i'm so excited I feel bubbly. This is awesome!!!

Please don't forget to tell me which arrangement you think is most appealing. Your advise could save a life.
