Thanks for your comments. I have been able to retake the photos on my gaming board, giving a better background contrast, white -> silver really wasn't a good idea. These pictures can be seen below. I have also been busy painting more of the Grey Knights - in particular a vulnerable dreadnought (classed as a normal dread - models just look alot nicer and give a more grey knight look) a rhino and 5 more purifiers, bringing it up to a full 10 man squad.
The dreadnought isn't quite finished yet, as I still have to paint the assault cannon along with the base. Also the finished dreadnought will have an autocannon - just waiting for Forge World to deliver it
I have also had a bit of trouble painting the rhino. Painting such a large model silver is quite hard. In my opinion it looks a bit flat, so and ideas would be great. I am also not sure about the red side door.....too much red?? Also, the hatch on the top is my first attempt at free hand. Yes, I know it is quite easy to paint a letter but it took me ages.
Anyway ill shut up now and let you see for your self. Please enjoy
