Line Drawings

This is my first attempt of a line drawing using a Stanley knife to cut out shapes and bring the colour of the card from the background through i thought one thing that went well was using the knife to cut out strips to use them to pop out forward making the piece have more shape to it and more depth using these pieces to over lap.
however looking back on this piece I can now see pieces which i would need to improve on for example the smaller objects do not have as much colour or detail added to them. a few of the additions are unable to see on this for example the the lower left corner of the middle object when using the addition of this I thought it would look a lot better however it does not show the back ground colour as much as I would have liked it to.
