Alright, I finished "v3" of the Brickmania bitmaps. This is more than likely the last poll I'll hold on the topic. Your choices are between the current, CVS ones, "v2" ones (the darker version of the bitmaps that appeared in the 'attempt two' poll", and "v3" ones, ones I just remade based on several "they need to look more 3d" and "bricklike" comments.
The new ones are rather similar to the v2 ones, but they have more of a brick texture, and a bit stronger highlights/shadows. Also note that the v3 ones have different textures on each color bitmap, whereas the CVS bitmaps and the v2 bitmaps have the same texture on each brick, just with different colors.
The winner of this poll (if it's by more than a couple votes) will probably end up being the bitmaps that stay.
