Having now read the item (I'm struggling with whether to call it a book, pamphlet, leaflet or other) I can say that it is short and sweet. The information that is there is well written for the most part. There are some issues with sentence structures and there is the occasional wrong use of word variations, but nothing major.
I have three main problems with the content as it is:
1. You mention in your text that the stone orcs have "A large lower jaw has tusks that protrude out from their mouth ..." and yet the drawing (lovely though it is) does not have these.
2. The sentences "... have made a special type of orc metal that is strong and causes more damage on hits. These weapons and armour are feared since they are stronger and tougher ...however can break more easily making them useless to some militaries." which completely contradicts itself. It is not until you read the section on Orc Metalstew that you realise that what you actually mean is that "the metal can on occasion become brittle and therefore prone to shattering." (feel free to use my wording in the text!!) For those who have not read this item this boils down to a Critical Fumble whereby on a roll of 1 damage is done to the weapon itself, bypassing AP and potentially damaging the weapon. You also don't mention if that damage stacks, though I imagine it would do.
3. I checked your Orc stat averages using rumkin.com and am glad to see that all your Str/Con/Siz/Int/Pow/Dex/Cha averages are correct. However your information regarding the Orc War Axe and Orc Great Axe is backwards. 1d10 (war axe) is far less powerful than 2d8 (great axe). With 2d8 your Minimum roll is always going to be 2 and your maximum 16, an average of 9. While with 1d10 your min/max is 1 and 10, average of anywhere between 1 and 10. Simply not as powerful.
So I think I might agree with Soltakss,I would rather get more pages - between 6 and 8 maybe - in order to gain more information. The 1$ price is great but some backgrounds, professions, racial magical spells and family life details would be good.
I'd also recommend sub-headings within that massive block of text on the first main page, it's a bit daunting as it currently is.
Having said all of that I think this is a very worthy effort, but one which can probably be enhanced with very little effort! Well done sir, roll on any changes you make and also the next edition
(I've already submitted this to RPGGeek btw)
