Skinning is the best combined with Leatherworking, so check out my Leatherworking Leveling Guide if you want to level Leatherworking too.

When you hit 25, you will unlock Specializations. I would suggest having a little bit of a look through the specializations. Spend some time reading through them, then choose which direction you might want to go. But don't be too hasty with spending points just at this time unless you have a clear goal of which direction you wanna go. The Knowledge points are going to be the limited commodity that you will never be able to get enough of, and you will always want more of.
You will need 50 skill points to unlock the second specialization and 100 for the third.
Leveling Dragonflight Skinning
You can level Dragon Isles Skinning to 100 at any of the places below. Every skinnable mob will give you skill points up to 100.
There is always at least 3 Ravenous Rockfang up at the marked area. There are hyper-spawning mobs, so there is no downtime. There is also a quest mob there that has higher than usual HP. You can also pull that one if you have enough damage, and won't slow you down.
The Azure Span
You can also find a bunch of Bears, Goats, and Mammmots around this same area. They are all skinnable, so kill everything. The small "Calf" mobs only drop grey items, but they will die to AoE easily, so they won't slow you down.
The Waking Shores
The Primal Proto-Drakes at The Waking Shores have really fast respawn rate. Also, a lot of people are questing there, so you often can skin the mobs without killing anything.
