Thank you for the feedback. I was going for a Miller Cylindrical Projection, but since this is my first entire world map I am working out the projection and any advice on this would be greatly appreciated.

There will be islands that i will add later, and for the mountains, they are just place holders right now so i can work out where the major rangers will be. In the final there will be no mountains at this scale (20,000 x 10,000 miles). I have the ranges where they are because I started out with a pangea and cut it up into several chunks and moved them around until i came up with this. I then placed the ranges where two landmasses came together.
