Map the first two difficulties all the way, lazy bums.
Some newbies get pissed when their favorite song isn't mapped fully in the dif they play. Far outnumbers those who go "short is good!", trust me. Doesn't matter too much though. Just go through them and check for slider overlaps. There were a couple in the easiest difficulty.
orion's night:
Shake it up! This map really needs some intuitive jumps like so:
00:37:691 (1,2,1) - This is a perfect place for a pair of jumps. It has a couple of emphasized notes that are basically screaming, "jump please!"
Look for things like that. Simply doing this will make this map a lot funner.
Hard:
See if you can break up some of the 1/2 streams. Some of them just felt weird. Let me show you a good example of a spot where that hit circle would be better off gone IMO:
00:20:496 (5) - This is a great example. It just feels better if this hit circle's deleted because having it there goes against the flow of music a bit.
00:23:788 (10) - Same here.
Why does it feel better if those two hit circles are deleted? It's A. how the music goes and B. What you've already established with 00:18:483 (4,5). That spot has the same musical pattern as the two spots above and by deleting those two hit circles you would go with the flow, so to speak.
Look for things like that.
Otherwise, nice job. Guess I'll star it ahead of time since there's no point in you bugging me again if you decide to change nothing because there's nothing technically wrong with it and it's a bit fun, I just think it can be improved greatly if you spend a little more time on the last two difficulties.
