try to use some colors from these 2 donors, and add more details, try to vary with lines, and, to me right side looks great now, now go and add some (color) detail on left one, try to make some contrast..
and yea, if i'm wrong in anything i say, feel free to correct me.. these are just my observations and ideas ^^
keep up mate
