Ah Mr. Sternbach, you've made my year by replying, so thank you. I recall the photo you're referring to. I did my best to find it on the Web but to no avail. I know this version of the engineering hull is slightly different to your original concept but I'm trying to be as accurate as possible with the rest of the ship.
If any moderators are reading this, perhaps they could make the call of this thread is better suited to the artwork section? I will be posting more updates soon and Rick, many thanks again for your input. Please feel free to chime in again if you have any comments or critiques on this in the future.
