Drawing Techniques

These are a couple of the reference images I used.
My first attempt at three of the techniques. Was having an issue with my scanner so had to take very blurry phone pictures instead for now.
Am now going for the five day breakfast drawing challenge, because why not?! Will try and incorporate all of the techniques if I can, and learn more about them as I go. This is the drawing for Day 1 (scrambled egg on a toasted breakfast muffin, apple slices and a cup of tea, if anyone is interested ;) )
Another meal: carrot and coriander soup with potato scones. I put more effort into trying to shade this one and add more detail.
Reference image: my lunch. Corresponding drawing coming soon. Not sure which techniques to use yet.
It'll take me a while to understand these techniques more and use them correctly to start improving my drawings, but they're good to know about! I think I've started to think about the angle technique, negative space and the envelope technique as I draw.
