Three FCs: Free Commission

I drew these for three people from the Sega forums about a year ago. To make a long story short, I was going on a long vacation and wanted something to draw, so I decided to take requests to draw people's fan characters for free for a very limited time. I also thought this would be a good opportunity to practice drawing and shading Sonic-style.
I don't remember exactly who I drew these for, but I sort of recall the character's names. From left to right, we have:
Sonia the Hedgehog
Ray the Kangaroo
Cookie Chip the Rabbit

Before anybody asks, I do NOT take free requests any more. That was a special exception. If you want something from me, you'll have to commission me. Here's my price list: [link]

Critique not desired; these are very old pictures (as in, from 11 months ago. ) and even with more recent digital coloring, they're not exactly my best work.

And I apologize for taking so long on these to the people who requested them. I never take this long with paid commissions, trust me.
I watermarked each one separately so the commissioners can use the images of their particular character without the other two in it. Feel free to use this online elsewhere as long as you link back to my DeviantART account and leave in the watermark on the pictures.

And next on my Sonic-style to do list is to draw an adoptable I adopted. [link]
