gothboy, the real thing you need to focus on is not the graphics, the backgrounds, the 3d objects the items. You need to actually spend some time building the engine and not just collecting media.
By all means find a little media to use in the engine. But be realistic.
The stuff you've mostly presented so far, I have to tell you I feel you have no hope in using in a working program. Spend the next three months building the engine to the actual game itself, then you may be ready to find a few media items to plug into it.
Otherwise really, you are just fooling yourself. You'll have all these cool items/objects and really won't be able to use them for anything.
All the media in the world won't make a working program. It's just eye candy with no substance. Programs are more than that.
Just my opinion..
Everything happens for a reason
