A couple visual changes (Nothing advanced)

Okay guys, Ive been searching for HOURS. This is the fourth straight month that ive looked for these mods and I only found one mod **SIMILAR, which I will explain later. I wanted to know if ANYONE has seen the following (Or made the following):

1.)Red arrow on enemy mines (Similar to the green arrow on friendlys, but I want it to be red on enemies)
**This is the mod where I found similarity. It was the mines to missiles mod, but I DONT want to change them to missiles. I prefer the look of mines. The red arrow would be better.

2.) Warning for traps (Auto turrets, hornets, claymores, THOSE STUPID ASS SPIKES THAT SLOW YOUR CHARACTER, etc) It can be anything, as long as it is SOME sort of warning.

3.) Bigger/Badder explosions. (I love explosions!)
***I have found one mod, but its not very descriptive. If someone could walk me through it, that would be appreciated.

And lastly,

4.) Different HP bar (This one is not that important)
(Like with HAUSER instead of the basic character)

Thanks in advance, I would like if you can tell me what to do (Unless it has a guide), im pretty basic when it comes to modding.
