Older Kalmin  
In their ref they are 18, I’ve edited older Kalmin before so why not make a quick ref of them at 24  
Design changes:  
Unfortunately shirts don’t fit forever and Kalmin had to leave behind their favorite purple tank top and switches to a button up (rarely if ever, buttons the top two) still wears jeans, just a different color and changed to black boots. Kalmin later has a incident in which they refuse to wear bracelets a changes earrings. 24 year old Kalmin also has another scar on their wrist.  
Original lineart is by Hasbro and the edit was made by me
