There is a non-maintained list of graphics work here:
http://freeorion.org/index.php/Graphics_Work
It's not of much use though, and we haven't really had a working graphics lead for a while now.
My suggestions:
For immersion purposes, having relatively large and similarly-styled artist's impression of all the species, to include in their pedia articles might be nice.
Many of the ship hulls could use fancier graphics as seen on the design screen.
Various techs, specials, buildings, and similar content could use updated icons.
Some GUI icons for different part types in the ship design screen to replace the text button labels...
Update some of the tech category icons in on the tech tree filter widnow, particular to make it clearer which are selected or not.
Feel free to suggest things that need updating if you notice them in the game, as well...

I renamed the "game asset" category to "art music text assets".
https://github.com/freeorion/freeorion/ ... t%20assets Should hopefully be clearer. If there are enough issues specific to art and it seems useful, the category can be split.
