Indeed! That is a great looking cab!
It's a great design, and I love the website too!
I especially like the control panel layout, and your artwork design.
I'm certainly not knocking the excellent job you've done,

but the black monitor surround you have is quite barren, and it makes the monitor look small compared to the cabinet (even though 18" is a fair size).
You are obviously a talented designer, how about you design some sort of purple lines type border?
It will frame your monitor very nicely.
Just as an example, here's a picture of my bezel (not made by myself!) - It seems to make the monitor look bigger than it actually is (it's 19"), as there is less space around it.

Just an idea - looks great anyhow! Well done!
