painting signed corelli?

i need to identify this painting unable to match the artist signature online

 

If there is a signature there, I can't see it for 2 reasons - the"picture" is not straight up and down and we can't see letters in the mess of painted lines.

 

Hello, Nadia! I've taken the liberty of flipping your photograph and reposting it as a Full Image so it's easier for everyone to see. Photographs of the work, both front and back, including frame shot from straight on would be helpful. Also an in focus close-up photograph of the signature. And if there are any stickers, labels or handwritten notations on the back, please post an in focus close-up photograph too please.

Now that we have a decent photo, it looks like there may be a signature of either 4 or 5 letters, written in very thin letters in script close to the lower right corner.

 

AND when I enlarged this image it looks like, as @Bakersgma says, there are a bunch of letters in this much more readable siggy, but also looks like some are in that darker section at the end.....maybe the OP can look carefully and pick them out as my mouse has suddenly decided to go crazy as I'm getting off as soon as I can hopefully get this posted!! Might be a date twds the end too....

yes i did notice that there is possibly date on this painting but because of the background extremely hard to read I have spend hours online trying to match the signature. here is the close up to the signature of the painting which probably wont help. In ref. to the back of the painting I will check and confirm tomorrow as I do not have access to it right now. thank you so much for all of your input and Debora for re-adjusting the picture.
