You can, just do what I did by searching the web for 'How to make…' diorama videos or procedures. Most of the scenery I use comes from Woodland Scenics. They also have lots of ‘How to…’ videos on their website. I purchased another parts cabinet just to keep all of my diorama materials in (grass, sand, gravel, rocks, field grass, foliage, etc.). I will be more than happy to help you in any diorama project you may want to start. For trees, look for videos on how to make them using strands of bare small gauge copper wire to form the trunk and branches. Ground scenes (armor, guns, infantry, etc.) are the easiest to start with. Figure painting is a challenge, but I’ve learned a great deal about it over the last few months (how to do faces and body/uniform shades) and I’m no artist. The use of washes is a must for weathering effects and I’ve come to use them regularly. Let me know if I can help.
