Sonic FC Brawl 2: Prelude Cover

I finished the sketch to the cover of the prelude!

NOTICE This is just a sketch. Can anybody help me with creating a lineart?

Thoughts of the contestants (top left to bottom right):

Ring: I have enough strength and agility to win this thing!

Ashley: Umm... hi?

SiGMA: These wimps don't stand a chance...

Moon: Let's fight fire with fire!

Laura: Wait... this isn't how this should be fought...

Hammerhead: I've trained for this for a year. I think I know what I'm doing.

Drake: Ummm.... how do I sign in...?

Melissa: You shouldn't underestimate a sword.

Rayna: This should be interesting... a few teenagers fighting a veteran adult...

Shino: Hmm... I wonder if this Chaos emerald will be enough to win this battle.

Punky: I wonder how they will react to a Cyborg, hm~?

FreeMan: I pray for these people who are competing in this 'event'...
