Both are awesome and super easy too. And for your ‘concept’ . Of course dude there’s got to be at least one videogame which has characters like that. Also, if you want it to look exactly like It looks like in the pic (i’m talking about the anime/cartoony look) you’re gonna have to take a look at ‘cel-shading’ (I think that’s what its called). And also, you have to try doing characters by yourself, you know like, seeing which way suits you the best. so try them all… also, remember. ‘Practice makes perfect’
good luck bro !
