FBX Importer Quality not soo good as in Blender

Hi guys, i am new to Blender and Unity, . . . I've done editing an Object in Blender 2.49b, let's say a statue with cool details with a lot of sharp spikes, but the problem is when i import the object, the detail is reduced (the spikes are kinda blunt, not as sharp as in Blender), so i have problems with $$anonymous$$gh detail object . . . .

When i render the object in Blender, it's perfectly like i want, but it's kinda looks "not as i want" in Unity . .

can anyone tell me how to solve t$$anonymous$$s problem ??
