is my Tri Count enough?

Hey,

so there are two characters in my game. At the moment they are 3k each. The background is simple geo with textures as the environment. Is this too high for the characters? They will be running, jumping etc.. A few items flashing on and off, such as power ups and a small amount of particle effects. Only when something is destroyed and kept minimal.

The end device is an Ipad with Retina screen.

Any thoughts on if I can push the poly count and should drop it would be appreciated. I'm hoping to have baked in textures with no interactive light aside from a shadow.

Cheers!
