First thing find a very good reference photo that is large enough to see fine details. You can use the reference photo for a couple of things, color reference and also to get the birds proportions and specific features. The more details you have as reference the better your bird drawing will be. What type of colored pencils do you use? I find Prisma Colored pencils are absolutely the best as far as intense color and laydown on the paper. You don't get the scratchiness like you would get from a cheap colored pencil. Also use some paper with a "tooth" textured art paper is the best because it grabs the color from the pencils better and in the long run you end up with a better picture. If there are any other questions that you have just post them. If I can help I will. I love to do colored pencil drawings. Good luck with yours!
