Amateur sketchbook-learning to draw

[touches]

Well i am posting these drawings just to improve my values in art.. Any criticism whether harsh or helpful or funny is perfectly fine.. as it would motivate me to become better

I have posted the reference pictures from which i have made the value sketches. So please help me to improve

Since this is the first time i am posting i may have not followed cetain rules.. if so i am sorry

Thanks for the advice... when i practice the values for the first few sketches i draw the shapes correctly but as i am trying to improve only my values i just tend to make a rough outline of the shape.. well i guess i'll have to stop that
