Hey,

-I see in all the exercises you're line is not as confident as they should, they're not continuously smooth , they're is alot of chicken scratching.

It seems that you don't use your shoulder doing these lines . I'd advise to try and use you're shoulder confidently and redo the ghosted lines exercise.

I also think you're boxes are very similar, I think you should try different angles of boxes using the Y method, try to apply that in the 250 boxes challenge.

i also need some critics on my assignments to move to the Next challenge, please help me with that.
