No disrespect intended. Just my honest...blunt answer. 
I would consider that to be a lower to mid range pastel.
Here's what I look for when I am looking for a pastel.
And, for the sake of the examle...I'm only talking about "normals". No Anerys....Etc.
1) Overall look. Speckling/black??? How light is the animal? How much contrast does the animal have?
2) Side medallions. Are they faint....Or, dark??? Do they have low/medium/high degree of black within it?
3)The belly. Is the speckling/black? Again, low/medium/high.
4)The side of the tail. Where the tail bands are. Is the speckling/black? Again, low/medium/high.
5)The tail. How bright and vivid is the tail? Does the color of the tail seem to be "worn away"?
6)Saddles. Are they tan. How much black is there? low/medium/high.
7)I will even look at the "moustache". Is it all there? Or, does it appear to be smaller than normal. We've all heard this technique talked about with hypos.
8)Color. Now this has nothing to do with an animal being a pastel...But, I want it all!! 
I am sure I can think of more....But, I'm tired. 
So it really is an overall reduction of black. And, there are many variables to it. It can't be helped unfortunately. So, I look at all these things and then think to myself....This animal will darken with age.....Will this be a light or dark adult?
Now, back to yours.
1)Look pretty clean for the most part.
2)From what I can see...A little black...Not much.
3)Not available.
4)Looks pretty good from what I can see.
5)Pretty nice tail. It does seem a little worn away in places.
6)Look to be tan with a little black in them.
7)Not available.
8)I see some color. But, I also see it on the aspen bedding as well. So, I'm not sure what the true color is completly. It looks like it will tan out as an adult.
And, again no disrespect intended here at all. To me, this would be a starter pastel. If you want to start a new line this would be a good one to start with. Find another one that matches all the critera....And, then selectively breed these animals to create a new pastel bloodline.
Personally, I'm lazy. I don't want to....Or want to give the time for something like this. I don't like to reinvent the wheel. I would rather keep my eyes peeled for a great looking pastel which I know will create better looking babies. And, isn't that what we all want? (For the most part) Nice looking adults and babies that will surpass the parents.
So, let me reiderate. I'm not trying to down your animal. I think it's nice. You wanted an opinion. I gave you mine. 
This is not the "Pastel" law. This is just what I think and look for when I am looking for a pastel.
My 10 cents.
Happy Holidays,
John
