Seeking opinion on sell sheet.

The font is not the most readable. I get what you're going for, but it's a bit rough and there must be better, similar options.

The spelling and grammar needs work.

Needs a components list.

Don't forget to add your phone number if you're sending this to publishers. Email is ok, but interested parties may wish to call.

Invoke the game’s theme and marketability. I'm not sure you've done this .. I'm not quite sure if there is a theme (I see a paw print, and the name fetch, but I don't see anything else that matches with those (diamonds, pearls, gold?).

Perhaps too briefly describes the mechanics, but perhaps not. This one is up in the air with me.

Find a way to highlight special features.

Overall a decent start, but I am not quite sure I know what the game is all about just reading this - it needs something more to grab my attention and tell me exactly what it is I am looking at, without getting overly complex or difficult to navigate the page.

I agree with Krone. An established publisher will likely see a document with poor grammar and English and think the game is just as poorly made. That may not be the case, but people tend to make those comparisons.

Secondly, a publisher is going to want a game that is 100% done. In other words, it has been playtested through and through, including blind playtesting (not just you, your friends, and family). If it's just a concept that hasn't gone through rigorous testing and refinement, they will likely notice and decline.

Here is a sell sheet template I found on the BGDF forums. This shows you want kind of information yours needs to show.

My main concern would be the font, I found it a bit difficult to read.

I appreciate you're not a designer so don't want to go too heavy on the look of it because I think it's OK, but making it a little more readable would be helpful!

Look at it this way, without the nice art the odds of interesting a SMALLER publisher are more difficult. They may know of a few people, but the art style may be different and not match what you would like for your game.

Demonstrating that you have already found an artist who is capable and willing to do the artwork is a PLUS for them!

In the business of designing games - designers usually bare the cost of the upfront art. And hope to get a return, when the game is Kickstarted or sold in stores.

So while you could ask for a reimbursement - I would not. I'd rather chuck it into the "Got me published - because I paid for some artwork" category. And let the Publisher pay your artist for the remaining artwork.

It's like stores that have "loss leaders": stores sell things inexpensive to attract buyers into the store hoping they might buy MORE than planned and therefore recovering the loss with the purchase of additional items.

That's kind of what I am saying: it's like an investment you make to hope to attract the right Publisher.

Asking for money from a Publisher is not the best way to start a relationship. Smaller Publishers have more limited funds - and you should be HAPPY that they take your artist and produce your game. If you have to sink in a few bucks, well that's what it takes to get your game "out-there"!
