Would have been great if you managed to keep the art styles somewhat consistent... Or at least decently professional, since you are going to commision it. Keep up with the great work!
(BTW, if you really thought AI images are worse than any hand drawn images, you would've used hand drawn stick figures or whatever you could crudely muster yourself, but you do you and 'PR' like this is valuable :P)
I would not have used drawn art as I hold myself to a very high standard when I create art. The art style will not be consistent as this is still a one man project (excluding the wiki). Art is expensive and takes time. It's easier to commission a bunch of artists rather than one and wait multiple years. I'm very new to commissioning, and I'm experimenting by seeing which artists I would like to consider working with again.
Also, any free art anyone makes, even if it doesn't remotely match the other art styles, will be added just due to my appreciation for it.
