He LimeZu, thanks for answering my questions on Twitter.
I have come across a few possible bugs/issues with a few sprites when building the character generator tool I mentioned to you and wanted to report them.
1) Some of the "Hairstyle" sprites have the "sleep" frames at the bottom of the sheet offset incorrectly and the hair covers the face when overlayed. They seem to be 8px or so too low on the hair spritesheet when compared to all the other hair variation.
See example here: 
The Hairstyles affected are:
Hairstyle_5_1 to Hairstyle_5_7
Hairstyle_12_1 to Hairstyle_12_7
Hairstyle_18_1 to Hairstyle_18_7
2) It appears like some frames may be missing, although it could also be intended but I thought I'd mention them anyway just in case.
Hairstyle sprites jump from 22 to 25 (23, 24 missing?)
Hairstyles 27, 28, 29 only have 6 variations, all other Hairstyles have 7
I've only looked through the character generator folders so far but I will be going through the packs in the next days so I will make sure to let you know if I find anything else and will send you a link to the tool once I have added a few more features.
Also, do you take suggestions for ideas for new sprites that you add to these packs or are the additions already planned out / on a roadmap somewhere?
Thanks!
