You did a great job of posting the image!
I've been unable to come up with anything yet about the artist. However, I did find an ad on craigslist.org where a similar type of painting is for sale and the artist is Garcia. The painting is for sale for $80.00. If you contact the person who has placed the ad, he or she might be able to tell you something about the artist. I will keep looking, though... Link is here.
I'm quoting something from the ad below because the ad will expire after awhile.
