>>1813254>>1813257For the eyebrows and eyefolds, only use the nodes at the tips (meaning you only have one sharp node on each side) and shape them.
For the blush, you got the use of tips right, but you need to shape the blush lines more. Basically, if you leave them how they are, they look very fat in the middle and have little direction. Shape the blush lines at the tips, in the direction the blush lines look like they are going. In this case, the blush lines go less in a certain direction, and instead bend in opposite directions at the tips, to give it a more curvy look. Do it that way and it should be good.
For the pant leg and the poofs of the sweater, you just need to treat them as separate shapes. Look for where a line ends (ie: the tips in this case) and then look for where other separately drawn shapes will hide under others. This way, the folds on the clothing will be more obvious, instead of being confusing when done as one shape. Something like that gets better with practice, since you start to understand art a little more when you see how the better artists drawn their folds/creases.
Since you're doing this in Ai, I'll throw in the file so you can get a better look at how the shapes are drawn, node wise. Don't worry about the thickness choices.
