Wreckage suggests a nose-over. Amazing that the wing is essentially in one piece but folded forward 45 degrees. Everything ahead of the wing crushed - everything behind the wing virtually undamaged.
Stall? Sudden pilot incapacitation?
Weather indicates highly variable winds (swinging through 200° range) and CBs in the area (Tropics can get very small, localized CBs).
Winds closest to the time of the accident (190, 260) seem to NOT favor the runway normally used in the normal easterly trade-winds (07) and apparently used for this takeoff. But with CBs nearby, winds can change a lot in 15 minutes.
All suggestive - but insufficient data....
EDIT - but of course engine failure fits the known data as well.
