As someone who started out painting the LOTR figures, I sort of know what you mean.
Remember that, as they are based on the movie, they have to appeal to their fan base, first and foremost, that\'s why they are already in a dynamic pose, that\'s why they have little creative scope- who\'d convert a charging Aragorn from the HoHD? There\'s simply no need as it\'s already got that feel. This, however, hampers the model- it loses out on the conversion aspect- people look at it, acknowledge it, score it, next mini please.
In addition, on a picture you cannot appreciate the scale of the piece as in the discussion in another thread about the Hobbits, which again hampers scoring.
As DR said, people tend to stick to the movie colour scheme- I stick to it- which again rules out another area for creativity. With exceptions being Goatman\'s freehand work on Arwen\'s cloakmor Peter\'s shield on Boromir.
*Forgive me if I got your names wrong*
Basically, in order to get the top marks, you have to do a flawless paint job on the mini, or something extra in the examples above.
The conversions that I do see tend to be small ones, weapon swaps etc; small, but effective.
I do, however, partly agree on the casting comment; I have an Elrond that had a mould line straight through his face, armour and between the scabbard and cloak which obscurred most of the detail. However, I believe this to be an exceptional case...
The LOTR figures are beautifully sculpted, yet need to be appreciated more.
