Welcome to CMoN and mini painting. Well the only advice I can give int he current state would be taking pictures int he daylight is good, but the background for them must not detract from the image.
I cannot really see the mini well in this picture.
Maybe a step outside for a quick pic in full light, or a backdrop behind the mini that doesn\'t pull your eyes away from the mini for inside shots. Some people like a blue to white gradient image that can be made in image editing software and printed out for this.
You can also get some tissue paper and put in front of desk lamp to diffuse light on the side of the mini to make it stand out more in the image.
The mini is looking like it might be a great start, but the picture itself doesn\'t show it off that well. Try taking pics a couple different ways until you find the one way for you and your camera that will give you good images that focus on the mini.
Then it would be easier to give you advice on your techniques when we can see your work.
I do note a bit of shine, but unable to tell if it is form the light source or a glos paint on the mini. If the mini is glossy, one thing to remember will be to find a matte finish for your final minis to remove the shine in places where there should be flat color. Places needing to shine again you can use Future Floor Finish, or another clear acryllic to brush over and get the shine back.
If you live in an area that carries them you could use Testors brand Dullcote Lacquer as the matte finish to remove shine, and Glosscote Lacquer to make gems and such things shine again after. Both should come in brush-on and spray versions if you can buy them where you live. Dullcote you will want to spray on, and Glosscote you will want to brush on. Use an old brush for this so you don\'t waste a good one, and don\'t forget to buy the Lacquer Thinner also made by Testors if you do brush on any Gloscote to clean your brush. (Future Floor Wax is clear acryllic and water clean up if you use a variety of it for your gloss.)
