Ok - here's your B&W conversion.
On the top row if you need to remove three ... suggest the first from the left (too light and almost identical to the one on far left of bottom row), either the 4th or 5th from the left, and either the last or 2nd to the last on the right.
On the bottom row ... remove the 8th from the left (the one with leaves), and one other in the middle somewhere - whatever you like the least.
Give me a few more minutes with it ... still contemplating the bottom row.
