I think the forms are good, one thing I will note is that the linework is a little scratchy in places.  a good way to practice unbroken lines is to draw two dots on a sheet of paper and then try to connect them in 1 fluid motion. and as it gets faster and easier you can put the dots further apart. 
hope this helps:]

Thanks Andrew ! 

I have been trying to draw longer lines in recent practices. It's a bit harder and I mess things more often, but when I get it right, I agree it's much better. I hope I'll manage to be more consistent with it ! I will definitively try your dots method !
