Unfortunately, funkiness cannot be trimmed away...JMHO........to insure a true 1/4" seam use tape or postit notes to keep you on the mark...and of course, your cutting must be as accurate as possible....the three you show really don't look bad...there is a bit of "squish or stretch" when you join blocks together. Just sew slowly, pin much if you feel it helps and wow! It will all come together....
