Of course you'll find Arabian breeding... they're in all breeds. ;)
I agree with you in saying that you can't base ALL Appy's because of small eyes, stubbern temperment, etc.
Like I said, I've seen some AMAZING Appy's working at the Supreme that whipped Quarter Horse but during Reining and Working Cow.
Like ALL breeds, you get good, level headed pretty horses, as well as your bad, conformation sucks, stubborn jackasses.
My Arabians are all dead quiet, and some can be harder than heck to spook! But I've seen some Arabians so out of it I wouldn't touch them with a 10 foot pole. LOL
I actually do happen to like the head on your Appy stallion.
The only thing I'm not fond of in Appy's in the excess amount of pink skin, and the colouring (and, like I said, I also do not like the colouring on Paints). Any sort of spots on a horse I just can't get a liking for.
I don't have anything against the breed, per say, just some of their traits (such as above) that I find undesirable. But that's only my opinion, neither right or wrong, really.
There are some amazing Appy's out there doing amazing things.
They just aren't for me, and others like. :)
