Hi Tony! Welcome to the forum! I’ve heard of players using their own 3D terrain and also saw some pictures on the facebook group, but I have to say that your scenario looks outstanding.
May I also ask which miniatures are you using? They don’t appear to be from the original game 
If I find anything I’ll definitely let you know, but kudos to your work, it looks really awesome. Keep us posted on the games you play with your custom terrain!
