Can anyone give me some advice on toning and shading?

You can use some shading techniques such as cross hatching and circulism

If you don't have the proper blending tool you can always use a cotton swab instead of your finger

hope this helps

yellow and blue because thats what i remember, im not sure tho

soft,hard and rough for soft would be a pillow or a stuffed animal hard wood floor or a table rough paint
