The tamers alliance

You sir, are to be commended! Definitively a superb start to what could be an awesome piece!

And yeah, I admit I'm a little bit disappointed at how Regan and Lizomon are kinda small in the picture, but at least Lizomon makes up for it with wingspan
And man does he looks scary without pupils. ._.

Now, on to some other more detailed comments for the rest of this.

From what I can say of Reiji's digivice, yeah you did made it a bit small. Watch version indeed.

I can see on what you would mean on how Betamon looks a bit retarted. It's most likely that if you hadn't made his eyes as big as they are right now, he might have looked better. But still, he was greatly drawn.

Not much really that I could say about Tetsui(although he fights in the Frontier spirit style), but overall he was well drawn too. More on that later.

Very good representation of Regan and Lizomon too, despite the obvious size matter which you mentioned. The more shredded ends to Lizomon's wings also add up to his 'rough' looks, not to mention, the pupil-less eyes seemingly make him look really more feral.

Considering the fact I know little to nothing regarding Jaymi's characters I can't say too much on the work you did on her, but I can say it was well done too!

Also, excellent work on yourself and Imperialdramon, who certainly must have been tricky to draw. Although I can say it's kinda curious to see your character have that kind of crazy look on its face.

Overall, the other thing I want to add up is that you have managed to portray each and every of the characters very well. We can really see much on their personalities and characters by the way you've drawn them.

And thus, excellent work!

PS : I am certain it would look even more awesome in colors
