Ok, nvm. Connection returned apparently so I can update everything
So... first, the BG...
I'd like to clarify the reasons I choose the current BG (it took me 3 days to find it, so...): The giant tree in background, well, that's obvious as to why; the general "anime theme" of the BG is because I wasn't able to really find anything fitting which was also "real" and since Miku is itself an anime character I thought of a vague "resemblance" with that; the girl in the front is supposedly "dancing" imo, which resembles well the music's motif; the "dark and gloomy" feeling you guys are perceiving I can't feel it at all (I actually think the opposite on this matter: the dark surroundings give more emphasis to the pink, which is the real protagonist of the song); last but not least, wtf, the BG is the last reason I would have expected here, seriously. Just because someone got mad over an inappropriate BG on another map (not mentioning who, since everyone does it already) this doesn't mean we all have to go around and accusing every mapset with an anime BG of "inappropriate BG" since I can't see the problem on my mapset (the fact you don't like it doesn't count, obviously, and I really spent 3 afternoons to search for it because there wasn't one fitting).
If someone can Photoshop a dancing Lindsey on Harbyter's BG suggestion I may consider it.
Last note: the video was placed because of this, actually. Since there was no "relevant" BG to Lindsey I thought of using the video as a supplementary material for it, that's all.
tl;dr The BG is fine, you're just nitpicking on nothing
Back to the actual mods:
@Gero Darn, I thought all snaps were correct since both Okoratu and CB told me to use the actual snaps (maybe I took this too far and mapped snaps I shouldn't have) and also the last 2 QATs posting on this thread didn't mention anything else...
While I'm aware of them being human and not being able to be "perfect" I'd appreciate an unique post where all the QATs speak their mind, or at least do a general check on it in order to avoid the same DQ for the same reason... (Let's say the QATs can DQ a map and lock the thread as long as there is no post from them with all the problems on the map taken in examination. If that would be the case I would gladly wait even a couple of days for that, since I would be sure that fixing those problems leaves me with no more doubts on my map's state. Just throwing an idea...)
@Bakari Fixed everything you mentioned besides the matter with the general SV on the Easy: while I do understand the reasons I also think that the difference in distance from x1.5 to x1.0 isn't that big after all. (above all because it is an Easy diff...)
Also, I didn't really understand what's the problem with the slider shape (on Normal) since it doesn't matter at all if it's a plain curve or just a decoration, but whatever, it's not a big deal to fix anyways
I hope that's all, if anyone has something else to add "speak now or forever hold your peace."
Updated with the fixes and no BG change for the aforementioned reasons.
EDIT: I gave kudosu for Bakari's post only, since Gero already gave himself the kudosu on second post
