Everyone has a different way of viewing art. It could be the way your brain perceives the colors or lack of them, what stands out about the piece to you personally and/or just in general, and your art style preferences because not everybody takes interest in the same type/style of art. :)
A concert hall is usually a big hall: big enough for an orchestra to be on the stage. A small concert hall, designed for just a few performers (as in chamber music) may be called a “recital hall”.
