Adjustments to my 3D model, Blender ...

[Napoqe]

Hello everyone.

I'm here to ask for help (if you want to help me), if to how to adjust the 3D model depends on not much effort ... if any tool for this? Or other ways? I wish do this
current model in a black panther.

I think I've already made a good base.

You can use symmetry modifier so you only need to make one side of the model. Or, some people said that sculping then retopo it is easier.
