A Portrait with Plumeria Blossoms

I enjoyed drawing my Cherry Blossom portrait so much (Click here to see my blog post showing this piece) that I decided to do another portrait. I was having some trouble deciding upon a flower to use for this one so I asked people on my facebook page to come up with some suggestions. The winning suggestion was plumeria. I had never heard of this flower but fell in love with it's lovely shape and beautiful color immediately.

Something that I had played around with for the first time in my Cherry Blossom portrait was the idea of keeping the portrait in black and white while adding a pop of color with the flowers. I added the color using Adobe Photoshop Elements. I enjoyed the final look so much that I decided to try it on this one as well, though the colors of the plumeria blossoms are MUCH more complex and I have never been very adept at photoshop.

This is the original black and white portrait done in graphite

Here is the portrait with the plumeria blossoms painted.

Which do you prefer?

Shall I continue on with this series? 

If I do continue with it, which flower do you think that I should incorporate in my next piece?
