In a true pentagram you would have planets (not angles or other points) linked by an aspect called a quintile (360/5) of 72 or 144 degrees apart. (Astrology allows for a fudge factor, or leeway from the exact aspect called an orb, but it's pretty narrow for the quintile-- no more than a few degrees on either side of exact.
Is this what you've got?
Quintiles generally involve talent plus the ambition to make something of those talents. Those talents can be inferred from the nature of the involved planets, their signs, and houses.
Unfortunately the astrotheme charts are really difficult to read. Can you try again on the free charts pages at Astrodienst www.astrol.com ?
A real pentagram would contain aspects called quintiles (360/5) which your posted chart doesn't show. Astrodienst doesn't display them in the chart, but you can (please) include the chart called an aspectarian which shows the various planetary aspects, including quintiles. Then don't include any aspects to chart angles or asteroids, as it just clutters up the chart too much.
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.
