Hi Shana
First let me thank you for the good words you had about my 2 paintings. I did appreciate very much.
Regarding your problem, I will first say that I am not myself an expert, as I don't know how to manage to upload better pictures ( I saw some in the forum that show picture a lot better then mine in details, size etc...  . But, for the problem you are experiencing(????) with your photos, I would suggest that you do not use flash. Try photographing your painting outside or in a room where you would have good outside light.
If not, use balanced neon bulbs (like Natural Light for exemple), once again without flash. The problem with flash is that it will reflect on the shiny surface of your painting, especially if you varnished it. Another solution would be to use 2 flash of equal color temperature, one on each side of your painting, hoping that they will balance each other.
Here is what I can tell you from my experience, and I say again that I am not an expert in the matter.
Sorry if my English is not perfect, but I hope it will be clear enough for you to understand what I mean.
Have a beautifull day
