New leaked concept art from The Force Awakens

Yesterday, a couple websites, TheForce.net and Makingstarwars.net, have revealed new leaked concept art images for The Force Awakens, along with early sketches of BB-8, two new aliens, another new X-Wing pilot, and a new kind of Tie Fighter never before seen.

Concept art images of BB-8, New X-Wing pilot, and the two new aliens:

These concept art images of BB-8 and new aliens are really cool works of art, but what is surprising is the sketch of the new X-Wing pilot. Why? He looks to be a new type of alien that I have never seen before. Plus this is the first time I have ever seen an alien as an X-Wing pilot.

Also here the new alien drawn as a rebel technician and as a speeder bike thug:

Next here are some revealed concept art sketches of a new style of Tie fighter:

The sketches of this Tie fighter were inspired by a MB&F Music Machine 3, a luxury music box, built by a Swiss company. For more about the music box, check it out here. I think it would be a great design upgrade for the new movie.
