1. Why is texture
so important to have in your sketches?
It shows different compositions in the sketch. It makes different things stand out out. If you don't have texture it won't look as realalistic.
2. Why is it
neccessary for you to have several references of each animal and each
background? Explain.
So you can refer back to the pictures and it can help you draw your sketch. It is very helpful and will make your sketch look better if you have references.
3. When you look at
your sketches are you able to see which sketch is the strongest and will make
the best print? How do you know this?
It has the best composition. It will show more of the lights and darks and where things are better if you have texture and good compostion. If you don't have it, it will just look like a bunch of lines and it won't look as good.
