Cool! Try using the same line size unless it's mastered like Zee-Rex, haha, just saying it doesn't look even when the lines are different sizes, also try making the neck less thick, and the shoulders are a little wide, other than those things you're doing great

Tips: yea just like he/she said make your neck a little less thick and ur shoulders little less wide...But u rlly are doing a great job sis...:p
