Hello
General:
BG size 640x480 and have a real poor quality, you must find better one
Your ComboColors inconsistent through diffs, you need a real good reason for this
Inconsistency in Source, put Stepmania in source on all diffs
That also come for tags ^
Light:
00:42:231 (1,2,1,2,1,2,1,2,1,2) - 10 circles in a row can be boring to play
01:03:304 (1,2) - doesn't look good at all, check this guide
t/37194&start=0 and pick some sliders
01:07:987 (1,2) - same^
01:10:328 (2,3) - also this one, no flow no structure
alright, technically this diff is fine, but have no flow and structure at all, you need to check this guide for flows
t/86329also we have great guide for beginners in mapping
t/122533don't be offended but you will need to remap a lot in this diff after reading guides, this is common for first beatmap btw :3
Standard:
00:42:231 (1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1) - NC spam here is not necessary, also the same for 19 circles in a row as for Light
other from that seems fine but anyway check this diff for possible improvements after reading guides
Heavy:
00:42:231 (1) - again, pretty much the same, try to place some sliders here, and remove half of NC
01:04:109 (7) - don't see any reason to skip hard beat on 01:04:182 () - and put slider on 01:04:109 () - instead
01:08:792 (5) - ^
01:13:475 (5) - ^ and so on
that style remind 2010 maps, I don't say that bad but eh :3 this is hard to sightread and hard to play
Challenge:
00:42:231 (2) - move this a bit to make more visible
00:42:816 (1) - same as for other diffs
01:04:109 (2,3,4) - maybe add note on 01:04:182 (3) - and make stream
also hitsounds doesn't give feedback to player, try to make notes on kiai more audible, especially this doubles
Good Luck!
