These MOCs are pretty cool and have a lot of personality, something a lot of MOCs are lacking these days. Nice mix of new and old parts.
Some tips for taking better pictures:
1- Have a good background
What you have here is fine, a white background would probably be worse for these MOCs, but that white stripe is distracting.
2- Camera settings
This is probably because the camera was set to a longer exposure, which is bad for moving things (or in this case the whole camera)
Look for ISO in your camera’s settings, usually I have mine set to auto, but you may have to change it manually. Smaller numbers are shorter exposure.
3- Lighting
The lighting you have now is usable, but far from perfect. Most of the time you want to use white light, instead of yellow. (you can see what color the light is on the lightbulb box) If you don’t have white light you can color correct it afterwards, or use natural light. I currently have a lightbox setup, with desk lamps shining from the left and right, this way no heavy shadows are cast.
