Any suggestions?

I don't see any sign of you being stuck. you'll have to give us a little more info. This is starting out at a much higher level than I would expect from someone your age.

From my experience with colored pencils, yes, you need to plan and sketch every detail before you start adding any dark colors.

White fur can be done with an embossing technique. You draw with an empty ball point pen and then use a blunt colored pencil for the background so that it can't get into the embossed lines.
