Oooooooh good job Lawy :D You improved alot ( pats ur head on a job well done) :D the shading is smoother and you have more tones! Great job ^^ I will only give you two pointers,the lightest tone should be lighter(I mean you can add more tons after ur lightest. Your current lightest would be the 3rd tone in the gradient so you can create 2 more tons), the number 0 tone is white so keeping that in mind try having the lightest tone just a little darker than white. As far as the shading goes, your doing great :D the white gaps have reduced alot, keep that up and try to have even less white gaps like in ur darkest there is no gap and its smooth.
