I'm still of the mind that the main comic and the nsfw stuff are drawn by two different people (somebody had floated the idea that the husband was drawing the main comic).
I'd argue she draws it all herself, she just goes from hand drawn for most of her stuff, to heavily referenced / possibly traced for some of it, her porn falling into the latter category. She is comfortable, at least complacent, with drawing stiff cartoon mannequins free form when they are just standing around, but for anything more complex she references and she is too amateur to layer it without it sticking out.
For example, this is obviously drawn without reference:
maybe reference, but no heavy reliance:
(these were from different panels btw, I made these collages initially to show her copy/pasting her own work)
Look at the lenghts she goes to not to draw hands, or draw them poorly:
then look at this:
I'm not sure if the hand was traced or drawn from life for once, but the phone looks like a photo under a filter.
Britney is traced from a photo.
Note the level of detail she gets from a photo versus how she barely knows what a t-shirt looks like when she is left to her own devices.
That isn't just her trying harder to get Britney Spears 16 year old tiddies just right, these are skill level differences with a gulf in between.
There are many more examples of this, but I'll leave it at this last one
where her tracing is actually decently integrated:
I'll grant that she drew this:
but this is BLATANTLY traced:
I'm not going to critique her porn in detail but let's just say that all I've seen falls under traced/heavily referenced, so it won't look like her regular stuff.
Also, Ellen, the difference between you and your daughter at 13 is that your mother was normal and you draw porn of yourself and post it online next to comics of your daughter.
Hope that helps.
