Here you can see that I made the homagaunt's body considerably lighter overall than the warrior I was using for the color template. I was not paying attention or really looking at the warrior while I was painting the hormaguant. This picture was actually taken after a couple of washes with the original dark green base color. What's done is done, but what can I do now?
Try to Fix It
I could try a few more coats with a dark wash to make the overall color better match the original, though this may also throw the color blance off. If all else fails, I could just paint back over it with a dark green base and start over. I have only done four models like this, so it wouldn't be too much work.
Match the Warrior to Hormagaunts
I have only completed the one warrior. It would not be difficult to bring it up to match the hormaguants, but I am concerned that the lighter skin color will not have as good a contrast with the other, lighter elements of the model. On the other hand, the lighter green may show up better on a table with less light. I would also have to be careful not to get green paint on the chitin plates or scything talons.
This is how they look on the table with more normal lighting (no flash). I think the more highlighted skin looks better, but it is hard to say which would look better on the finished product. I suppose there is only one way to find out! I think I will finish one or more of these hormaguants so I can properly compare and decide. I'll be sure to let you know how it turns out. Let me know what you think.
