Its very hard to write something about the painting as you didnt get us more details. This is the reason why my answer will be based only on my opinion.
First of all, because of the background of this painting, I probably guess that this has to have been painted aproximately at the and of 19th century or the a beginning of 20th. Anyway, the style of this image is old school/a bit exotic. Because of this, I guess that could be modernism/postmodernism/Art Nouveau painting.
So with this conviction, I tried to search for a similar painting style by some artist on auction sites, sites like wikiart at so on.
In my opinion, this is not a painting done by a world famous artist, but I have to admit the style of this paiting is really good.
In the end when you want to know artist by this painting, you should give us more details as size, weight and picture of whole painting even with picture frame. If you really want to know that artist you should propably consider an auction valuation.
P.S. This is just my opinion about this painting, if somebody hae more details about this, I would be really glad to know them. Last but not least this is just my opinion as you know with this information I can't do more. So please dont blame me for that.
