I just mentioned brush/filter spam because it is the most common thing done in photoshop. I didn't see your picture or any of your work. I didn't want to offend you. Your logo is nice.
But saying this is about copy pasting is just wrong and made me think you are more of a beginner with photoshop. It may be done but it won't win. I put a lot of handwork in mine. Actually I never use brushes or filters in my works. I do everything by hand. You can spend pretty long on the shading of each part and the shadows. That's what it is about.
If you have an idea for a (in your opinion) more skilled competition feel free to PM me. I'd be glad to make it.
