Love them...I so want to use multi-exposure one day but masking & blending a few shots works too. Nicely done.
I have more difficulty with multi-exposure as you have to plan the exposure values so much more to get the look you want. I like the composite photos but you have to be careful that one position doesn't interfere with another, especially in tighter photos. I originally wanted to have TV, video games, and sleeping in 1 photo but I didn't have enough space and didn't plan it well. I could have done it with a wider shot but I didn't want to frame to much more in the shot than the couch and end tables.
