Featured Abstract Art Identification, Help needed for artist

I bought this from a shop in Brooklyn NY, and as you can see, it's signed. I can't make out the name though it appears to maybe say C. Rivas, or E. Riva, or some other close combination. As you can also see, it's dated 1992. Can anyone help please?? Thank you.

 

given to a lover....... nice colors !!!

Or a sandpiper, with that thin beak.
