please excuse the delay for this answer, your request somehow went unnoticed...
Could you give us more precisions about your problem, namely which EvoluteTools plugin you are using?
Did you obtain this result with EvoluteTools T.MAP? If so, the next version will come with smoothing options that will help making the faces more uniform. Before this happens, you can also optimize your result using EvoluteTools LITE, by flagging the edges for length optimization.
I hope this helped, otherwise don't hesitate to give us more details.
