Thanks for all the kind words folks.
I was largely unsuccessful creating the water tiers how I'd imagined them. And got sidetracked during my failed attempts. I've not given up, just learning new skills and will one days revisit. My creations are limited by my knowledge of TG and I tend to fall short at times.
One day I hope to be like many of you where I have a vision for something and just go and create it with little or no constriction. Wow, reading that sounds so far off and exciting to think of that day!
