Yes, thanks.
Your chart makes some interesting patterns, but I wouldn't call it a pentagram.
The main patterns are a T-square involving Mercury, Saturn, and Mars (+ Chiron and your ASC,) and a yod involving Pluto, Uranus-Neptune, and with Venus-Mercury at the tip.
With a T-square, the involved planets are involved in a stressful relationship, as they are joined by two squares and an opposition. The planets in a yod are sextiled, and then joined by a pair of quincunxes to a third planet (or pair of planets.)
With Mercury extra-strong in the sign it rules, ruling your Virgo ascendant, and conjunct your mid-heaven, this would be the planet to develop and emphasize.
