I'm tempted to use the "wrong" arm arrangement just to make a point that little **** like that shouldn't matter one damned bit. Sometimes I hate doing stuff for you guys.
I have to agree... The pipes of relevance (thick as they may be) are getting clogged by a lot of things that you should normally dump in a big truck.
It's not the exact form factor that is important, it's the impression. I think the un-edited version of the lion Mjn used was the best so far as far as facial impression, overall posture, and drawing style goes. It's like a lot of other stuff that is accepted in the FreeSpace Upgrade project - many models have artistic freedom in improving the design, and as long as it is identifiable as the original but made in higher definition, it usually as quite acceptable.
It's not like the lion being in slightly different position will adversely affect mission balance or identifiability.
That said, my opinion about this kind of edits...
Moving arms and legs around in a drawing is more likely to damage the overall impression of the drawing unless you are really, really good with what you're doing... case in point the switched arms look silly because the chest is now discontinuous and the right arm looks quite thin. Tail was improved, but I would rather leave the limbs alone, and either use the drawing as it is, or do something else.
