Moody,
This is one of the most impressive aquascapes i have seen on here by a normal TFF member. The rocks are fantastic where did you find them.
I was so impressed i photoshoped it and put a golden ratio grid on, hope you don`t mind.
These are the things i noticed that personally i would alter and just see how it looks. Only minor adjustments and i may be totally wrong and well of the mark but here is my 2 pence worth....lol i am only constructively criticising because i think it looks awesome and maybe could benefit from a minor tweak, IMO !!!!!
Have a look:
See the two rocks on the left, i think there sides are two parallel, the one slightly more central could be tilted a little more to run alongside the left vertical dividing line, in the position denoted by the pink arrow.
Finally, the two rocks just slightly protrude the horizon line. Maybe it is to do with the photograph dimensions which have scued the golden ratio lines, BUT it may be worth just pushing them a few cm further in the substrate and see what it looks like with them a little lower, somewhere around the horizontal pink line.
In my own personal opinion, i also think it would look cool with a nice stem plant, rotala sp. say, growing against the rocks in the middle left segment.
I may be talking out of my bum, but it may be worth having a play next time u have your hands in the water just to see what it is like...!!
lol
Nice one mate, Very Very Very impressed!
Chris
EDIT: forgot to mention, the arrow heads mean nothing, it was the only tool i could find to get a straight line!!
