Wow. That picture of Spike is just breathtaking. I love the lighting you used. And Spike herself looks so soft and floofy. And ditto to what Daisy said about the tail.

I love your shiny icons too. They're always so sparkly and happy.

As for colored pencils (I definitely commented backwards), I'd say get them from the internet. You can check the usual places like ebay and stuff. Or, you can make a post to artist geared livejournal communities. In my experience, I've found that livejournal offers a great buyer/seller medium as well. My roommate sold t-shirts that she got from Goodwill at more than double the price she paid.
