When creating builds from scratch out of styrene sheets or other non-predetailed plastic, what processes do you use to make them more visually interesting, given that real Transformers toys often have a heck of a lot of mold detail? Do you - - use pregreeblied kit parts or leftover Transformer panels as components or inserts? - copy existing Transformer mold detail and mix it up a little? - build your own greeblie panels out of whatever's lying around? - etch the blank styrene in random techno-artistic patterns? - have a set of processes you use to generate appropriate mold detail? - leave the styrene blank and smooth, because you like it that way? - something completely different?
