The models are coming out fine. The NNM is fantastic. I can't even DREAM to try... I think you are nuts! You can definitely produce paint!
I am in NO position to criticize your painting skills (far superior to mine). What I could do I to try to give you a few hints on photography. I think the quality of the pics is ROBBING us fro a great peep show.
So... few questions. What are you using to take pics? You phone or a camera? If you are using your phone, you need to clean the lens before taking pics. As I remember, you keep your phone in your pocket... this means the lens gets lint from the clothes and smudges from your fingers. Take the cover off and clean the lens with a paper towel... it will improve the quality of the pics by a million percent. Hmmm... is a million percent mathematically possible?
Anyhow... then the next step is to get you a light box. You produce way too many cool models not to have them save for posterity. The light box does NOT need to be an expensive or complicated afair. Get a BIG cardboard box, paint the inside black. Now, you could get some nice light sources for LOTS of $$$... not worth it. The trick is to get WHITE light from two sources. You can take two small lamps and put a white (natural) light bulb. These lamps can double as PAINTING light sources! You want to put one of them in the upper-front-left shining towards the lower-back-right corner and the other in the upper-front-right shining towards the lower-back-left corner. This will cancel the shadows.
Flash is your ENEMY. Think of yourself as Malcador the Sigillite and the Flash as
Lorgar (after the Horus Heresy). WAIT!!! Do NOT smash the flash on your camera! Maybe not your enemy... more likely not your ally. Avoid it. You got plenty of light (above).
Now, Narcisus has a GREAT link for backgrounds. I need to get them and print them. Anyhow, pictures should be taken from the front (slightly up) so you can see the front of the model (like the 1st pic), but not so high that you see just the heads (like the last pic... but I know you were just showing all the models on that!)
Hopefully this will help you to take better pics!
PS: Paper towel for background is not good. Is is not 'white', it has 'relief' so it scatters light (makes pic look unfocused and scatters light) and is porous (so it absorbs part of the light)... end result, pic looks fuzzy.
