It depends on how much models you will have at once in real-time. If you are working in a wrestling game, probably you will have four players at once?

That file size dont seems to be a big problem, however you can optimize the model reducing the skin resolution (ex: if you are using 1024*1024 textures you eventually could reduce to 512*512, it depends if you are making close-ups), or you can reduce the model polycount.

If your model size will increase much more than that, then you have a problem.
