First time I've really looked at results of one of these and one thing I must say, is how hard it has to be to do the judging!
I read what everyone else said before I looked at the pics, but I have to say, number one is quite amazing and looks like a perfect woodland scene with such strong greens and excellent lines in those trees. The time it must have taken to get such perfect vertical positioning and not make anything stand out and spoil the overall picture deserves recognition alone. But I love it and taking nothing away from the rest, all I can say is this one and possibly 5 or 6 others would have the winning vote from me.
Number 4 has immediate novelty value but my first thought was "should have gone to specsavers" lol it's a very cool design but would not hold long term appeal as some of the others would, I feel. I don't know how you guys judge these in your own minds, but the basics of initial impression, (wow factor) coupled with how long you can stare at it before wanting to move on, both matter to me.
Its so great to look at tanks of this level. It should as it's done with me, bring most folk back down to earth and re think their own designs and capabilities. That said, its always going to be a personal thing and in the end, thats the great thing about this hobby.
Cheers
