Good, but don't assume that since the letters are adjacent in our language they will in others- I can think of no reason why E/F, M/N and V/W would be adjacent. I'm creating an english version of the Obish alphabet (I'll make the Obish characters too eventually), but I've eliminated 3 or 4 redundant letters and added about 5 more that have no reason to be letter combos.
