To those (if any) who play this piece, what are some of the more difficult technical aspects of this piece, and things self should look out for before blindly jumping into this piece? 
Now that is a question! (The first one wasn't completely stupid though, IMO, but I have no clue about that).
Well, as you said, the "intervals-part" (first part) is really easy - for a Liszt etude! Well, actually I could sight-read it considerably fast, without too many mistakes, and also it`s just Allegretto, so no super fast piece here
Anyway, the E Minor passage after that has some jumps in it, with chords, especially RH, well, practice it, it is not so darn hard. Then the intervals story again.
But well, the next thing is mean! glissandi, parallel in both hands. I think this etude is pretty good to actually master this technique, but it is really not so easy (the most difficult part, I would say. Although once you have it down, it is no problem. But it hurts...

)
And then there is this 32th note passage, well, could be a problem because of the hand-crossing, and because you have to move all over the keyboard with the RH, and that at quite a speed... perhaps you better look at this and the glissandi before starting. The rest is easy. But only notewise! You have to make sure that you play like an orchestra, especially the "intervals-part". Don't know, my edition says: imitando il Flauto /il Corno (imitating the flute / cornet). And that is very difficult for sure.
Okay, hope this helped a bit... Still, take a look or two at all passages before beginning.
Best luck,
