As JDM as possible, i can't see any features that would make the skin JDM style. Seems like many people kinda use that term here and there meaninglessly...
About the skin itself, doesn't look too bad, nicely done.
this skin i did make has to look like the old safetycar of the KNAF (knac nederlandse autosport federatie) this is the result, it isnt uploaded to LFSW
bud you can do that
