Everyone else nailed your painting +/-\'s, so I\'ll go for the photography. Your pics are a bit dark and I see some strong shadowing. Generally, 2 lights is minimum each shining down at about a 30 degree angle and off to the sides of the camera. A third light in the back to wash down on the mini and kill the remaining shadows is even better. Look at a portrait studio in the mall next time and notice their lighting. Recreate it in miniature.
The type of lighting matters as well. Standard incandesents are bad, too yellow. GE\'s Reveal bulbs are better, the blue tint helps kill the yellow. Halogen bulbs are even better as they give off a truer light.
Finally, check into a diffusion box if you wnat to get serious about taking good pics. See my sig for a homemade one or check on ebay for a pop up tent one.
You are off to a great start here and I am not knocking, just showing ways to improve. Keep at it. Enjoy it.
