I need help for my Avatar.

I have decided I would like an Avatar but never really liked an idea until now.

I'll try to give a motivational description and leave artistic creativity to the artist.

I am wanting the parasite that sits on the tongue of the fish. Just the parasite with the fish cropped out.

Next I would like to place it either on the shot of Coach Miles's head, on his tongue. The shot where he is getting the gatorade bath and his mouth is open.

OR

A head shot of Coach Miles where the Parasite could sit on top of his white hat.

The motivation to keep in mind is the effect of is the Parasite along for the ride or in control?

I realize that what I ask may be difficult so thanks for trying in advance. It will most likely be my first and only Avatar.
