a few questions about graphics

hi, i am making a new graphic look for one game engine, and i have three problems:

1. i don't know how to successfully anti-aliase picture, i have the cogwheel in the middle of the image and the author of the engine told me that i need to more anti-aliase it. the picture can be found at: http://ukazto.com/?img=1713355,pozadi_inventar.jpg
2. the second problem is, how can i make a simple 3D button effect? author of the engine told me that the pictures is too sharp.
3. where i can get some good renders of "dead"? i have a picture with cross which saying "YOU ARE DEAD!"

i am remaking skin from ancient and fantasy to sci-fi look, i have only 3 images left, but i need these 3 points to successfully complete it. i am using adobe photoshop v10.0 cs3. thanks in advance for any help.

The help on this subject is going to be minimal here I'd recomend finding a more specilised forum, and I hope to see these changes on completion.

Good Luck dude.

You can make an object look like it is 3d by using a gradient. Then maybe fool around with the outer glow to add thickness to outline. Photoshop will definitly have a tutorial/help function.

and about the anti-aliasing, I'm wondering if you could find something related to steganography. But I know it's a big thing with digital photography because they alwant such high rez.

don't know what you mean by "dead" though. making logos or a poster or something? all i'm going to say is watch out for watermarks since it sounds like you're copying work online.

it's all my work, i did it in photoshop, i cannot use any public renders because of engine (text etc.), i have good blue mixed background by me (you can see it on the picture) but i need some cross, which is used to display when the character is dead. i cannot make it myself, i can only change it to blue and that's all.
