Good Morning Maggie
Once again Maggie thank you and I will be redoing this shot on my days off.
Good Morning, Dave.
I like this image better than the first one, although again, the background is too light and the focus seams to be on the raspberry and the leaves. Now, although it is nice to see the reflection, I think it all depends on the viewpoint and if the reflection is helping your composition or not. In this instance, I feel that from the angle that the shot was taken and since your object line is slim and horizontal, the reflection takes up too much space and makes the flower float in the middle. It needs to be grounded, so I think a crop from the bottom would definitely help. Something like this:
Now I realize you may not have software to do this but for $10.00 a month, you can get Photoshop CC and Lightroom and you will always have the latest and best around but at this point, you may find it too much to take in all at once. There are alternatives that are free that will allow you to do all the basic things and a lot more. I found a list for you, although I cannot say which one to use as I haven't used any of them but I know of a few that I've heard people use, for example, Picasa and Gimp.

Now back to your photo. Also notice in your photo where the front of the rose is not in focus and the raspberry is as are the leaves. In my mind, the rose is probably your primary subject and on your camera, you can set it to one focus point and then move that point to where you want your camera to be focusing on, the pretty part of the rose. Now, I have no idea what you are shooting with but many years ago when I was just starting out, I had a point and shoot and couldn't move that point, I would turn my camera to focus where I wanted, half-press to hold the focus there, then turn the camera to the composition I wanted, then full click.
As for the light on the front of your flower:
Depending on the ambient light, you may need the white board to reflect light to the front of the rose. You will need to experiment.
A few years ago, I bought a large piece of white foam core and (1/4"thick) and cut it up into pieces and you might be able to find some at your local walmart. They are extremely light and I just slide them into the space between my desk and the wall. They are white when I need them or I clip on black or white poster board as needed. It just makes everything neat and easy and allows me to run the poster board low and curve unto my surface so I don't get a seam at the back. This set up is very versatile as you can use white or black depending what your situation demands and actually any color poster board. Last year, I did a shoot with water refracting through glass vases and glasses and I used lined wrapping paper to get the undulations I wanted through the water.
Most important of all, is controlling the light so you are not getting light on the background, keeping enough distance between your object and the background will help the background melt away. Slightly folding your black poster board to make it slide unto your surface will help avoid any seam lines.
Dave, I know this seems like a lot but it really isn't. Do not be discouraged. You have set yourself up a difficult task. Taking a photo with natural light with light surrounding your subject is quite easy, as you want lots of soft light. (huge window with white curtain or sheet makes for beautiful soft light). Tackling a dark surface with natural light demands a harsher smaller light to separate from the background and severe controlling of where the light is going. So take it slowly and start with just blocking light from the background and see if that is enough, then add flags as needed.
Here a photo with a black background with natural light that I took this summer. It's resting on a black box with a bit of cotton lace taped to it and the background is simple black poster board:
Again, don't hesitate to ask more questions or for clarification. One day, this will be second nature to you. You won't even have to think. You will always be on the lookout if you are in focus where you want to be, if your composition leads the eye the way you want it to, and how light can make whatever you are shooting interesting and exciting. Best of luck, Maggie
