The Fallout: New Vegas HUD has always looked a little too bulky in my opinion and just needed a little tweaking to look modern.

This edit makes the HUD smaller, cleaner and less intrusive. I tried my best to make the HUD look simplified but still vanilla plus.

HUD Edits - 

The two main bars have been moved to the corners and have been scaled down for less intrusion
The quest and stage indicator have been moved more to the left and closer together for a more clean and compact look
The top left Vault Boy and indicator have been moved up closer to the corner and scaled down slightly
The XP indicator has been scaled down, made to be more compact and moved closer to the right
The Rad meter has been moved closer to the top right and has also been scaled down
The pickup prompt has been edited to get rid of the border in between the WG/VAL and item name as I felt this would look 
cleaner and more compact like the other changes, some people may not like this change which is understandable and you can 
turn the border back on in the "Edits" ini if you wish

There are many more edits that I haven't listed but are viewable in the images section.

Compatibility - 

As stated in the HUD editors page the mod is compatible with the following:
    Vanilla UI Plus (v8.72)
    Revelation (v0.61)
    Vanilla HUD Remastered (v1.83)
    oHUD (v1.1)
    HUD Like Fallout 4 (v10)

I personally only use VUI (Version 8.70) so I can't be sure of how this edit
will look with other HUD mods.
