I hate to disagree with Micaela but if you look at the pic that Sapphire posted and at Micaela`s the first pic, rt arm, Left side as we look at it,, there are three little dark dots on the upper arm !!~ They are also on the one Sapphire posted !! So if these two are not the same,, it would be unlikely to have the same dots on two unrelated statues !!
You did say,, that the one Sapphire posted was not yours,,did you not ?? Did you purchase this on ebay ?? I just need some clarification here !! And are the places on your statue that you say are the result of cleaning,, a lighter silver color or is it a lighter color than the original ? Bronze is a mixture of copper and tin mainly, and is a combined liquid when poured at the foundry, there should not be a mixture of colors unless it was coated after pouring and that was done to keep a few things the same exact color wth a clear coating !! Bronze will sometimes darken with age and that is not a bad thing !! It should not be two totally different colors !! If Micaela can help here it will be easier since it is difficult to tell much from pics !!
