I just have a couple of questions regarding your thought process during the creation of this concept. 

[indent]1) Have you read the Jace lorebook? How well-versed are you in the Jaceverse's lore?

2) Given that he is essentially Jace's dark reflection, does this mean that he doesn't have IBS? Have you thought about what this means for his power level, considering that Jace's IBS is the source of his power?[/indent]

1) I have not but I have skimmed the Wikipedia page

2) For every personal defeat regular Jave faces in life, Dark Jace will grow stronger. While DJ doesn't really have IBS, all of the crying it causes Jace to do results in power gains of greater or equal value.
