In that last interview you did, you mentioned how your art in Isaac is cringeworthy to you now and that there's things which you "don't want it to look like that anymore". Are there any specific examples you could elaborate on regarding their designs and why you don't like them now compared to how they've been updated for Rebirth? (such as certain enemies, items, etc)

the walls… i hate all of the walls in isaac.. they are all rush jobs that look muddy and undefined.. especially the wrath of the lamb ones.

isaacs body is lopsided, a lot of the womb enemies just dont look too great to me at all.. the eyes especially. 

there is something i hate about just about everything art wise in isaac :) but i like the enemy designs a lot.. just dont like how i drew them.
