Ok, I would love some advice please

my April goal was to finish Panda's quilt top - what I have done so far, I did a year ago just after Easter. It's come out a bit smaller than I wanted & I was going to add a black border to each square to make it a bit bigger & define them more - after looking at it this morning though I'm not so sure. It might be better as it is.

I've posted pics HERE and I would really really appreciate some feedback.
WDYT - should I just join all the squares I have (& make it a throw instead of a bedcover), or add black borders?

ETA - I haven't photographed them all but there are 25 squares.
