do you have anyone you look up to? someone who is a big inspiration? these people dont have to be real people, or the could be famous, or just everyday friends.
if that dosent help, maybe google a character generator? ive done that and it seems to work
Definitely just find reference pictures on Pinterest or something (you can check out my acc my at is greenteaxbabe I have a drawing references board) And get the sizing correct in reference to everything else in the picture. Good work tho keep at it!! <3
