In regards to wood blocks, I meant it used in this way:

I personally have found wood properly varnished and held as close to its natural form to look beautiful.
When it comes to artwork I'd say to go with what speaks to you. You are going to spend the most time in your place so you want it to feel the most comfortable to you. I remember when I first started decorating my place I had a box of crayola and a coloring book on my coffee table so that I could use it as a "comfort building" prop.
Got older and realized that my place should not be done with the females in mind, but rather what works for me.
I have vintage cardboard advertisements hanging up. I have an old New York Times headline from Kennedy's assassination framed and hanging. The reason they're on my wall is because I like the way they look, I appreciate their history, and because I stole them. I also have a vintage WWI Red Cross propaganda poster hanging up because it spoke to me when I first say it. Have a few pieces of artwork I really like and other knick knacks hanging.
That's me, perhaps these pieces would not inspire you. Treat your apartment as an extension of yourself. Surround yourself with things that "speak" to you. Just know that less is more.
I knew a guy who had an entire wall filled with framed photos of him on his trips. He enjoyed the reminder to constantly be traveling. Do what feels the best to you.
You can definitely mix and match furniture. I'm guessing you're on a budget. However think about the overall look of the room. You don't want to buy things because you got a good deal on it. Think of how everything will work with each other.

How much artwork or wall pieces you put up is up to you and the layout of the apartment.
Something to think about is putting up mirrors to make your apartment look bigger.
If you can't figure out what to put above your bed, a mirror is boss.
