In the orginal they were so blurry some I couldn't figure out what the painting was. I'm hoping they'll look better in the remake. So what exactly are some of the psintings that are difficult to find out what they are potraits of?
There are a few that aren't locations.
Let's see...here I think I see (from left)..not sure...Hyrule Castle from the side...not sure...and looks like two goats from Ordon.
Here it looks like a painting of the Arbiter's Grounds in the back and the Sacred Grove in the front.
Based on what I've seen, I think most of the paintings are just various locations in the game.

Well, looks like a couple of the paintings in TPHD have been changed into Zelda U references! I don't think we'll get much out of the paintings, but getting some more Zelda U stuff is always nice. I haven't seen anything for the Snowpeak paintings specifically though, so I don't know if those paintings have even more references or not.
