I can't help you. I'm a crafter. However, that little boy captured my heart. I have three sons who did this exact thing. It's a lovely portrayal of a little boy.
Others will help you with your details.
How delightful for you.
Hi Cathy! There are a variety of choices to blend your colored pencils with. There are colorless blenders in pencil form. Some people use a lighter color of pencil and extra pressure to blend their layers. There are also a variety of solvents that you can use...rubbing alcohol, baby oil, odorless mineral spirits to name a few. I haven't seen your piece yet, but simply applying additional pressure as you apply the last layers of pencil is often enough to do the trick. With wax based pencils, you can get too much wax built up and it can create what is known as "wax bloom." ...using a solvent, applied lightly with a small paint brush can help stop the wax bloom. Don't forget to seal your final image with a few layers of a spray sealer to protect your work.
