Some questions...

Alrighty! Thanks a lot!

Tamiya figures may seem small but they actually scale out to 35th better than most figures which tend to drift to 32nd scale or larger...

As far as base medium there is no silver bullet...I use celluclay a lot but it is far from a perfect medium...it tends to curl and lift easily and has a lot of shrinkage...plaster and other fillers are less prone to shrinkage but tend to weigh more when dry...

Best advice is try a lot of different materials and techniques and you'll figure out what YOU like best...there is no substitute for experimentation, trial and error and practice...

Just do it and post pics...

Any other suggestions would be great...

Thanks! i was thinking of using drywall plaster as well. Did it look decently good, and was it easy to sculpt and move?

i cut the limbs at places that move (i.e. knees, elbows) and reposition them as needed, filling in the gaps and sanding as needed.

i'm working on my first diorama s well and i cant really help you there, but i used drywall plaster for my ground work. worked ok, but took about a week for half an inch of it to dry.

For Tamiya figure size, its not just tamiya and zvezda that have stuff that seems a little wrong in size...when comparing my academy tank crew with my tamiya tank crew, the academy crew seemed about 7 feet tall.
