I know this is a Gimli skin, but the quality is outstanding and i even use it, even though I don't use it as Gimli.

(While we're on this topic you know skins sort of over-write each other right? Could it be possible you meant models?)
http://hiveworkshop.com/resources_new/skins/190 - Pretty cool looking skin
http://hiveworkshop.com/resources_new/skins/189/ - By same author, both look very good.
(There is a way to have skins per model, but if I recall you need to export the model, change the paths to the skins and re-import them, but I guess if they look good they probably are a smaller file size then models)
Anyways here are some models in the case that you meant models
http://hiveworkshop.com/resources_new/models/948/ - Dwarvern Paladin
http://hiveworkshop.com/resources_new/models/551/ - Dwarf Statue
http://hiveworkshop.com/resources_new/models/639/ - Awesome Dwarvern unit model.
(A skin for that model:
http://hiveworkshop.com/resources_new/skins/178/ )
http://hiveworkshop.com/resources_new/models/1060/ - Dwarvern mage
http://hiveworkshop.com/resources_new/models/1589/ - Dwarf Rogue
(Skin for that model:
http://hiveworkshop.com/resources_new/skins/276/ )
http://hiveworkshop.com/resources_new/models/2042/ - Dwarvern Clubber
http://hiveworkshop.com/resources_new/models/1967/ - Dwarvern Bandit
http://hiveworkshop.com/resources_new/models/2721/ - Dwarf w/ Hammer
http://hiveworkshop.com/resources_new/models/626/ - Dwarvern Slayer
(Skin for that model:
http://hiveworkshop.com/resources_new/skins/907/ )
If you think the file sizes on model's are big there are several tools that I use, which reduces the size quite highly, without losing any quality, they are:
http://www.wc3campaigns.net/showthread.php?t=86878 - BLPalletter - Reduces sizes of skins
http://www.wc3campaigns.net/showthread.php?t=83416 - MDX Squisher - Squished the size of a model
(The size of these doesn't actually show, the only way to see the size saved is if you compare a map with compressed to non-compressed, but it probably saved atleast 500 KB's of data in my map)
I also use this:
http://www.wc3campaigns.net/showthread.php?t=82558 Wc3 Image Viewer, and open the image, and re-save it at 75% quality, I don't ever notice a difference, but it saves a lot of space, sometimes it over halves the size of a skin
(Also keep in mind that World Editor itself slightly compresses the file)
Sorry for the babbling, hope I was of some help to at least someone.
