Here's something to consider: Do you like arranging smaller picture frames in a gallery style or hanging just one big artwork? I feel a gallery wall is tricker to create among the two. To make this easier, I've a few eye-catching gallery art works to inspire you. I'm not able to figure the way these pictures are aligned.. and it doesn't seem to matter whether these are symmetric or asymmetric; some have a few and some have too many; yet they are all extremely polished and elegant. There are tons of wall art gallery templates available on the internet in case you need some guidance. Or you might be able to just come up with one when you let your imagination wander...
