When your in Bryce, hold the mouse in the top left corner, file edit etc. shoud pop down, then go to file new and change the ratio to 5:4 and make it 1280 x 1024, or whatever your desktop resolution is, bigger the size, longer it takes to render, I got Bryce but still learning it made a sword in it, but the blade sux really bad, just a rectangled with a point, need to finish it and make it look like an actual blade.
