Short Answer: Yes, accountancy is suitable for you.
Long Answer:
Determination of Profession
1) Phasis
Mercury is around 24 degrees from the Sun. Estimating the relative speeds of these two planets, I would say that Mercury is not making a phase within +/-7 days of the native's birth.
Venus is 46 degrees away from the Sun, so we can say with high certainty that it doesn't make a phase within +/-7 days of your birth.
Similarly, because Mars is 3 signs away from the Sun, he will not make a heliacal phase within +/-7 days.
2) Midheaven
In this chart, the Midheaven point is in the 10th sign from the Ascendant, so we only need to consider one sign. That would be Sagittarius. There are no planets in this sign. Sagittarius is not a domicile or exaltation of Mercury, Venus or Mars.
One thing we may consider is that Sagittarius is the domicile of Jupiter, and since Ptolemy says to default to the ruler of the MC when all other conditions are not met, Jupiter may be selected as the significator.
3) Stars receiving the application of the Moon
Ptolemy said that a planet on the MC is fit to signify the profession, especially if the Moon applies to it. But we may want to consider the stars that the Moon applies to, even those that are not on the MC.
Note that I only use the classical aspects: the trine, the square, the opposition/diameter, and the sextile/hexagon. I also consider conjunctions but not as an aspect, rather as a different kind of relation.
We see that the Moon is in trine with the Sun but separating from it. The Moon is also in square with Jupiter, but again, is separating from it. Thus, the Moon applies to nothing.
4) 2nd and 6th Places (Maternus)
None of the three planets are in the 2nd or 6th Places (I use Whole-Sign Houses).
5) Stars that are pivotal (Maternus)
Maternus also considers planets that are angular or pivotal to be capable of becoming the significator of profession. From my limited experience, I agree with this approach, so I will include it here. Note that I use Porphyry Houses to determine the angles, but I also consider angularity using Whole-Signs.
Using Porphyry Houses, Saturn and the Sun are angular. By Whole-Signs, Mercury is angular. So according to Maternus, we want to consider these stars, presumably when the other conditions are not met.
Judgement
In my opinion, there are three potential significators for Profession.
The first is Jupiter, because he rules over the MC, and because he rules over the Ascendant. The second is Saturn, because he is pivotal (by Porphyry houses) and the MC point is in the confines/terms of Saturn. The last one is Mercury. This is because is he pivotal by Whole-Signs and he is in the 1st Place by Whole-Signs.
Jupiter by himself, signify money/wealth, friends, public affairs and magnificence. When receiving the influence of Saturn, it makes one concerned with lands, estate, foundations and farms. Though I really doubt this is the case for you since it also receives the influence of Mars, and Mars and Saturn are antithetical to each other in this regard. Jupiter is in Taurus, where the favourably placed Venus is, which bonifies Jupiter (makes it more benefic). Also, Taurus is quadripedal; according to Ptolemy, "...the quadrupedal signs contribute to produce employment among metals, in business and trade..."
Saturn, being well-placed but contrary to the sect in favour, may allow you to be capable in jobs that require structure and control, which is certainly good news for you if you decide to pursue accounting.
Finally, Mercury's position is problematic, since he is contrary to the sect in favour, is in his Exile/Detriment and Fall, but is in the favourable 1st Place, although he is not pivotal. He is lacking in both favourability and power to help the native to progress with regards to profession.
However, the kinds of professions that Mercury signifies include:
"...writers, superintendents of business, accountants, teachers in the sciences, merchants and bankers: also, soothsayers, astrologers, and attendants on sacrifices, and, in short, all who live by the exercise of literature, and by furnishing explanation or interpretation; as well as by stipend and salary, or allowance..."
So in conclusion, I do think that accountancy is appropriate for you.
