Yes, I do like them.  I've put them on my to-do list to have a play and see how they might fit into a mine-type setting, but will be a while before I get to actually do something with them (my list is quite long ).

I would advise though, that you don't spend any more effort on them just now ... if it turns out that they don't fit into the game then it would be a shame to waste your time.  If someone does want to use them, then they can ask for exactly what they want (e.g. some broken sections of track, or whatever).

You clearly have a lot of graphic skill with 3D packages - have you considered making any mobs?  See Torchwood's artwork.

I can't believe that cat!  Reason being, I have no artistic skill what-so-ever, but I seem to be able to use Blender to get reasonable (in my opinion!) mobs - but only if I can get a good image to use as background reference.  Your tracks are very good - so I bet you could do something with a mob!

Well, there may be a lot of nice looking mobs the people are showing in their stickies, but there are only a few artists who are creating fully animated mobs which is what we need.

But fair enough!

I didn't find rigging too hard using Blender ... there were some good tutorials out there, and for the small image sizes we currently have you don't need to be too detailed with your rig.
