UPDATE NUMBER 5.
DIO BUILD!!!
Good evening folks. So here it is as promised, the much anticipated diorama build...
So I started by sketching out an idea of what i wanted the final dio to look like. I have to admit I borrowed the idea of using a CD case from OutbackModeller's Hasegawee Egg-16 build (they do say the imitation is the sincerest form of flattery). This is what I came up with. Its done to the same dimensions as the CD case, so I know roughly what space i have to work with.
I then began the physical build of the dio by fixing a piece of plasticard to the top of the CD case using plenty of CA and a load of clamps.
Once the glue had cured, I marked out a 1" grid pattern over part of the base that would become the runway using a ruler and pencil. I then scribed this pattern into the plasticard using a Tamiya scribing tool.
Using some grey DAS Modeling Clay I then built up a small embankment to add some background detail and height. I also plan on adding a sign to the banking, but I'm keeping it a secret as to whats on it until later... I also sketched out some of the detail just to see how it would look.
Thanks to my Dad, I have some brass (PE?) lettering and numbering sets kindly donated to the build that will be used for the sign.
The base was then primed using Vallejo grey primer (my primer of choice), and left to dry for 24 hours.
I then went over the scribed areas with Mr Hobbies Flat Black to add some pre-shading before lightly going over it with Vallejo US Grey. This was then allowed to dry overnight.
Light weathering was then applied first using a Humbrol enamel black wash applied into the scribed detail. Once dry this was followed by a liberal brushing of Ultimate Dark Dirt wash over the scribed areas and part of the surrounding area. This was allowed to dry for 20 min before being gently cleaned up with a moistened cue tip/ cotton bud in a streaking motion. I was a bit rough in one area, but the raptor should cover it when its finished.
Whilst waiting for that to dry, the banking was airbrushed using Vallejo dark dirt (I think?

) to give a base colour to the grass once applied. I also added some small cork chips using PVA glue. These were then dry brushed with various earth tones to simulate small stones to break up the edge of the banking and make it look more natural.
Once everything had dried off, summer meadow grass was applied to the bank using PVA glue and a puffer bottle. For anyone that hasn't had the pleasure of using a puffer bottle, it's akin to a talcum powder bottle that you squeeze and the air blows the grass out. Sounds good in theory, but its a bugger to fill and goes everywhere when you use it!!

But, it gives reasonable results...
The more observant of you will probably notice that the decals have gone on at this point too..
So next up was to start with the runway markings. When scribing the paving slabs, I purposely made one of the lines run directly down the middle of the runway (Unrealistic I know, But at what point did realism enter this build?) so all of my measurements for the lines can be taken from this point.
I started by marking out the boundary line and the broken taxiway line.
Once masked out they were airbrushed with gloss yellow.
I then used my sketched plan placed over a stip of masking tape to create a template for the center lines by cutting through both layers with a sharp scalpel. This was then lined up with the centerline of the base and stuck down. A light coat of gloss white was then applied to give the appearance of slight weathering and wear.
Once this had dried the solid line for the taxiway and the curved line for the runway exit to taxiway (what's the correct name for this line? does it even have one?) were masked off and painted. The curved line was cut using an Olfa compass cutter, cracking tool, but would be better if it could do smaller circles.
SO there you have it... one diorama... with the exception of the sign.
The Raptor has had the decals applied, and is almost good to go! Just a panel line wash and the vertical stabilisers fixing on and were all done...
See you on the other side!!...
