Man, I should really do a concept like this too some time, I just never run into this stuff :/ Looking good, though that wall piece doesn't look that difficult to not use floaters on, no ? Or are you connecting everything as a single mesh ?
I was thinking the same thing vahl... I've forced myself to have more "soft" edges on the sides of pieces, but now that you mention it, I definatly strayed from that with this piece, I will go back and soften them up a bit (i just don't want to make it look blobby :( ) And as for following the concept, this was just a wip…
