It looks like it has good potential. As it gets bigger, place it so that part of it has good light and part of it has more shade. You'll (usually) get even more color variation with echinatas. I have a large "orange crush" echinata that is usually orange with blue streaks. If I place part of it under shade, the eyes will turn green and the edges will get yellow. It's pretty cool. Unfortunately it's getting all good light right now and is just two colors. Thanks for reminding me to move it around some. :) You can already see this effect with yours a little bit. The edges are green where it looks to be a bit shaded.
