Right now, your radii look far larger than what I typically see used for .090" Aluminum, although 6061 vs. 5052 would call for a larger bend radius. Generally, 5052 is recommended for sheet metal work, but some teams do use bent 6061.
The sponsor my team has does use a .25 bend radius for .090" 6061 T6 it does seem big but that's what they call for for 90* bends. Other angles will be different though with BD and BR I just haven't put those in.
