Your drawing is very pretty and attractive. I think you'd better practice using clean lines. Clear lines will surely make your drawing obvious.

looks great! I think you did really well with the porportions. I think the line quality could be worked on, especially around the outline face.

Yo this is really good. If you want honest advice then it's the lines. There is an easy practice for this.

Also direction of lines. Angling the lines in a day with the shading actually makes a world of difference. Your line art is on point so if u can do this on the inside your stuff will be top tier.

This is what I believe you can do to improve, besides this your drawing is really good. :p

Very nice profile. The position of things (nose, lips eyes, eyebrows) is just fine. Check the eye, it looks a little off. You are coming along nicely. Keep up the good work. Practice and then practice some more.
