The Start of a New Adventure

This was my entry for the Sonic and the Black Knight art competition. Sonic and tails zipping thru Emerald Hill.

Alas not a winner but I'm still proud of this piece. I think the background is what let me down, a tad too bland maybe. Also; Yay Perspective~

Also Please Please PLEASE critique if you can plz. I can identify some parts where I went wrong but another opinion would be nice kthanks <3
