Wanna come with us? -sketch-

Some weeks ago, I finished Sonic Colours I have for my Wii... it's a very great game, and Sonic's and Tails' new voices is okay (I may told that in a journal). In the ending, the theme song came up.

I listened to the theme song some days ago again and, suddenly, I started daydreaming about Sonic running around with all the Wisps with him... then saw me, and invited me to go with him
..................................it just popped up in my mind.........

So here is the sketch of it.

Of course, it's not ready. And it's here you guys come in. I want to ask, do i have to change something?
All I know is I need to work on Sonic's hand... I don't know more than that.
I'm sorry if you can't see the picture orderly, took it with my mobile.

This will be in scarps later.
