Good start, Juul. You're the first to show actual progress work, and that's the main purpose of a campaign, isn't it ?
At this point I would like to ask EVERYONE to explain a bit about the technical aspects of their dio building when they post about their progress, with or without pictures.
In this case I can imagine that the blue parts are styrofoam. Where did you get that ?
What is the ground material ? Plaster ? What are the small pebbles ?
These things may inspire us and help newbies set their first steps.
Now about your dio.
1. I think you'll get into problems when you start detailing the corners. You may want to make sure the dyke goes all the way into the corners of your dio. Cutting off a few cm of the sides would be one solution, but that makes your dio smaller. So you need to add some of that blue product into the corners and beef it up till the dyke neatly goes all the way into the corners.
When that is completely done and cut to size, you add the plaster or other agent to sculpture this into a landscape.
2. By using a nice square block to support that dyke, you get a ... nice square dyke. You may consider to snip off the corners of that and model it a bit. It never hurts to make one or both ends a bit higher, or heighten the middle a bit. That gives some extra dimension to your dio. In real life (except maybe in Holland, true enough) things are not nice and flat...
3. I would suggest you fully model the blue underlayer, cut it nicely to size, etc. Only then start adding the plaster or other filler.
4. Since you already got this far, I'd suggest you trim the corners in such way that the side of your dio is nice and even. Then add some extra blue stuff and extend your dyke into the
corners. Try to work a bit on those dyke top edges : that dyke looks just a bit too flat.
5. You may want to glue that blue stuff on a wooden (or other hard) base. If you build on styrofoam without this support, your base may break.
You have still got a lot to do, but this is a good base to start.
The pictures you have there are a wonderful inspriation. To make this work, you'll need to make grass (have you thought of how to do that) and barbed wire (several options to do that as well).
Who the hell is General Failure, and why was he reading my hard disk ?
Where's my funky Iraqi general rank that was here on my profile a few years ago? Did they strip my rank, after all I've done for this forum ? Robbery!!
