Doesn't seem unusual to me.
Two points about angle of attack (alpha) though:
- Alpha is the angle of the fuse compared to the direction of flight, not the angle between the fuse and the ground. Since this plane is going up (I think) it's not that severe.
- Once the plane is off the ground, pilots don't use alpha as a reference. They simply keep the speed a certain number of knots over V2. If the plane is lightly loaded, this means a high angle of CLIMB (not attack).
It's a mighty nice pic but I can't help but think it might be a plug for your own photography

Hmmm. I'm not sure I understand why "angle of climb" and "angle of attack" don't correlate (if not being the same thing). Excluding fighter jets and high HP aerobatic planes, Vy is normally a smaller AOA (higher airspeed) than Vx (greater AOA, lower airspeed). But if we're talking about just holding a certain airspeed, then a lighter aircraft has a higher angle of attack/climb.

AOA= angle of the relative wind to the chord line of the wing
At slower airspeeds aircraft must increase AOA in order to keep the same amount of lift. The pitch attitude that an aircraft has for a particular AOA depends on the Angle of Incidence, or the angle between chord line and longitudnal axis of the aircraft.
if you watch a B-52 from the front for example you will notice the nose actually lowers quite noticably after liftoff due to a high angle of incidence. Most newer, or "supercritical" wing designs are more efficient than older wings and require less wing area to generate the same amount of lift. They are also capable of higher Angles of Attack resulting in "steeper" climb.
