Just FYI, I've added this to my (gigantic) graphic reference folder. As an aspiring artist (haven't been able to get to it, my life's complicated), I just love how cute the MC is, I just HAD to keep that style as future reference/inspiration. Both disneyesque and with a realistic feel. Hope to be as good as you one day. Maybe even add a credited cameo at some point. 🙂 In a distant future.
Here's a suggestion: would it be too much work to make this in color? Only by chance did I notice the character switches from blue to pink, that's an important plot element IMO.
