Might as well throw in my generic thing::
Topics like this are insanely common, there's probably more topics like this than there are mods made, and they just keep comming. If you want the most help possible it helps to give as much information, and uniqueness as possible.
Here's my generic written thing for these topics. if you want something specific give more details. I ask some questions in the below text as a small guide line:

For the occasional "What are your must haves?"

My generic thing are insanely common, there's probably the same number of topic like this than the number if time i used it, and i just continue to repeat the same thing to everyone.

:rofl:
But like he said, you need to give more detail... there is like NO DETAIL on what you want. Contrary to other, i don't ask 10000[...]00 details, but at least, just say something like: I want my game have a better look, i want tweak to make game feel... more real, i want a totally different game, i want to keep the game almost like vanilla, but i want to enhance it or anything like that.
The way you formulated it, you said: graphical improvement, tweak, balance, bugfix, etc
Formulated that way, its like if you just didn't wanted to formulated that way: Any category of mod, since you used {etc}.
Since it was unclear for what exactly you where looking for, i gave a list of some popular mod, but we can't help you more without detail.
