The problem is these are not being presented in any format that is easy to view.
I know you are a bright guy, so I know you can sort out your palette issues if you make that your top priority.
Making more units that are difficult to preview and so on won't help you solve this fundemental issue.
I posted 3-4 different ways that I've used in your other thread. Utahjazz, Steph and others have also responded (I think Hikaro and Wyrmshadow, etc). I say you stop work on this BMP and all other pending BMPs and sort out the palettes first.
What paint program are you using? I use photoshop, but I also have paintshop (for the included Animationshop program).
When you get the speckled background in a render, you can solve it one of two ways. Fix the lighting (sometimes hard when you're new) or open the BMP in Photoshop and use the magicwand to select only the two background colors (since I've never seen it make 3) and replace them both with 255,0,255 (magenta). Then look again at the various palette methods. The think is all the suggested methods work. There are 1000's of units which show that it can be solved.
Suggested tools to consider:
If you can afford it, Photoshop. If you can't consider Paintshop. Otherwise GIMP works and is free.
If you can find just Animationshop, it is around 29.00, get it. It is very nice way to make previews. It can open FLC's (or AVIs) and save them as an animated GIF so you can get more constructive comments. Trust me, people are excited that you are making units. The lack of comments have more to do with their difficulty in evaluating the units. If you can't find animationshop seperate, it is included with PaintShop Pro (this is how I got it).
Pedit is a useful palette tool. It is free. I used it at first, but now I just use photoshop.
