Haha, I just flipped when I saw it.
Here's a somewhat modified test version.
Maybe it can go as a bear? If you look with your bad yey... :)

The wide nose makes it look like a very angry pig :p.

Maybe I should just put some spikes there... :/
Meshes are so... complex!

Yes, you can just use the mesh directly (clipped as needed).  But using as a
height field, you can smooth/blur the image and otherwise modify it to look
more like stamped tin.  The mesh wiil be full 3 dimensionbal, whereas a
stamped tin relief would, in essence be more like a heightfield (i.e. only
one y value for each x-z point)

Hmm, yeah.

> Maybe I should just put some spikes there... :/

It could go as a bear (as you said), if the nose was a bit thinner.

> Meshes are so... complex!

Surely they are. I haven't even tried.

not really!! You can make it as clomplex as you want. It's like everything, 
once you start things become easier. It's a different approach, that's all. 
I can recommend Wings3D for a start.

Here is a link to a 16bit tga height_field image of a lion head (1.17MB)

You'll have to
scale <0.82,1,1.25>* whatever_ratio_you_need
rotate x*-20
and adjust the water_level
