Alternate Fighter Feats

This is my first mod and I'm bad at English, so please don't judge too harshly, but I'll be glad for any constructive criticism!

I added 3 feats that are alternate versions of Great Weapon Master, Sharpshooter and Heavy Armor Master:

Great Weapon Master → Great Weapon Mastery:

• []Great Weapon Master: Bonus Attack → Great Weapon Mastery: Furious Pressure (Nothing has changed, it works the same as before).

  []Great Weapon Master: All In → Great Weapon MAstery: Strike On The Spot!

  When attacking with a melee weapon that you are proficient with and wielded with a two-handed grip, the attack rolls take a penalty equal to your proficiency bonus, but the damage increases by twice your proficiency bonus.

  Example: You are a level 4 Fighter, your Proficiency Bonus - 2, your Strength is 16, and you fight with a Greatsword. You make an attack and roll a 15 on a d20. In this case, you must add 5 (Strength + Proficiency Bonus) to attack roll, but you have Great Weapon Mastery: Strike On The Spot activated. In this case, you add 3 (Strength + Proficiency Bonus - Proficiency Bonus) to the 15. Total 15 + 3 (Attack roll + Modifier) = 18.
  You roll a 3 and 3 on a 2d6 (greatsword damage dice), you also add 7 to the damage (Strenght + 2Proficiency Bonus). Your total damage will be 13 (6 - weapon damage + 3 - strength + 4 - proficiency bonus2).

  Sharpshooter → Keen Eye:

  • []Sharpshooter: Low Ground → Keen Eye: Don't Care About Obstacles! (Nothing has changed, it works the same as before).

    []Sharpshooter: All In → Keen Eye: All In.

    Ranged weapon attacks with weapon you are proficient with use suffer a penalty equal to your proficiency bonus on attack rolls, but deal additioanl damage equal to twice your proficiency bonus.

    Example: You are a level 4 Fighter, your Proficiency Bonus - 2, your Proficiency Bonus - 2, your Dexterity is 16, and you fight with a Longbow. You make an attack and roll a 13 on a d20. In this case, you must add 5 (Dexterity + Proficiency Bonus) to attack roll, but you have Keen Eye: All In activated. In this case, you add 3 (Dexterity + Proficiency Bonus - Proficiency Bonus) to the 13. Total 13 + 3 (Attack roll + Modifier) = 16.
    You roll a 5 on a d8 (longbow damage dice), you also add 7 to the damage (Dexterity+ 2Proficiency Bonus). Your total damage will be 12 (5 - weapon damage + 3 - dexterity + 4 - proficiency bonus2).
