Its been combining aspects from both the MWDA Mini and the new art. Some use the art as the main reference and other use a combination of both the new art and MWDA mini. The MWDA minis are also used for reference for sides that can not be seen in the new art.
Understandable, but compared to the actual art, the miniature looks off. Maybe I'm alone on this, or even wrong, but if this is the miniatures game of Battletech created by TPTB...I think the miniatures should be sculpted to the art in the TRO's...not the MWDA figures.
It's very easy to contact most artists to ask for suggestions & help on a miniature when referencing their art...but I guess it is easier to take the other route & use a figure that is already available, no matter how far off the art it is. Just wish there was some clear definition on what they can & cannot use. So far, minis that have been created from the MWDA figures don't seem to be well received.
