The proportions are pretty good, the face looks good and cartoony, the colour isn’t too bold, so far you’re doing alright.

3 / 10, it could be worse.

I would say, think about something that defines your character, or their’s or your own interests and incorporate that somehow into a design that fits the current style of the character, the more you have to show for a character to show they’ve had a past, have a future and have been around, the better they’ll be.

Currently you’re in early base stages so it’s all very classic stickfigurish, which is fine but if you want to up the standards you should consider story and design based on that, even if you lack anything really intricate, so long as you have an idea, you’ll be fine.
