I will work on this hair and have it ready for the animation update (might be next week!). It may be split into 2 hair sections (Bangs and Side Hair), so I'll let you know what the combo is if I split it!
For the eye colors, the whites of the eyes are currently hard colored (because it would mess up the universal palettes for like pants or hair). I will need to do some rearranging with the palettes and recolor the sprites first! I'll also aim to have that done for the next update.
Edit: Would you also like an ear option added that includes an outline?
Hi,
That would be great thank you and the ear option with the outline sounds amazing!
Also, I have a question. In RPG Maker, the default tiles are 48×48. For my game, I use 16×16 tiles that I upscale x3, so each original pixel becomes 3 pixels. I noticed that when I export your characters (originally 16×32, upscaled ×2 for RPG Maker), one pixel ends up being drawn over 2 pixels. This causes a problem with pixel consistency with my tiles.
If I try to upscale the characters to 3 pixels, their size becomes 48×96, which looks far too big. I can’t seem to find a solution. I feel like the characters would need to be 16×24, which would then become 48×72 when upscaled (already more visually appealing to me).

First, that looks awesome besides the obvious size differences! Sorry you are running into issues with matching your tiles. :(
If I am understanding correctly, I think the only solution would be to increase your tile size so they can scale x2 like the character sprites. I know, way easier said than done.
Thank you! It's thanks to you that I can have characters. Switching the tiles to a 24×24 base so everything scales ×2 would work, but it would mean rebuilding everything ^^. I think I'll keep the tiles x3 and characters x2 for playtests, and try to hire an artist to adjust the characters base to 16x24 at the very end. Thank you for the amazing tool, looking forward for the next update :)
The hair is done and the combo is Bangs 014 and Side 016. The eyes have also been recolored and changed to have their own palette instead of sharing the universal palette with the other assets. These will be added in the next update. We ran into some issues adding the tools to the creator, so it is taking a little longer than I planned but we are almost done fixing that!
Thank you so much for your update, I really appreciate it. I am looking forward!
I'm also making a bit of progress on my side. Below are the characters in x2 upscale and the decor revamped (x3). I'll need to put everything on the same scale at some point but for now it will be enough for my playtests :). Thanks a lot of all this

Hi Memao,
The new hair is amazing, thank you very much!
I ended up putting my tiles scaled x2 and developed a little tool to reduce the size of the character by removing some lines from the character sprite (for all directions) and can also add an outline.

That actually helped a lot to reduce their size so it fits my tiles better (sprites reduce by 4px at left and by 6px at right):


I will put this tool free to use if people have the same issue. I only tried it with your spritesheet but hopefully it can help the community with their spritesheet as well :).
