Yes, the work is phenomenal. I'm constantly amazed at the level of detail. Sultana, for instance (although I love Sourceress). I suppose it is easier for the artistic people - to non-artistic me it is mind boggling!
Flatfoot, the non-artistic me does seriously hope there is more than the 15 minutes testing you seem to have allowed above! LOL
Of course, you don't have to test breeding outcomes, that should save at least a week.
