Really nice skin. Looks really good.
But just a friendly advice for when skinning CtB. Don't skin out fruit-drop. Because if fruit-drop is skinned out then you won't be able to see the hyperdashes there can appear on dropplets, even if you have the fruit-drop-overlay skinned.
Also if you are going to cover the fruits with the overlay then just make the fruits completly white instead of gray. Because fx if the fruit-apple are made white the hyperdash when it appear on that fruit will also be brighter and there by easier to see when playing.
Some small tweeks I would suggest for the ctb version is delete the fruit-drop-overlay and only have fruit-drop (If you want to keep the gameplay white then also have fruit-drop-overlay) by removing fruit-drop-overlay the player will be able to see when the hyperdash appears on the droplet.
This will also give the droplets the same color as the combo color which imo will make the ctb version look more like the rest of the skin.
I would also suggest adding this to the skin.ini
[CatchTheBeat]
HyperDash: 255, 131, 0
HyperDashAfterImage: 0,0,0,0
HyperDashFruit: 243,182,17, 255
By adding this the color on the hyperdash will change from red to the orange you have been using. It will also remove the red afterimage and change the colortrail which appear when you do a hyperdash.
I know these tweeks are just my own opinion but i really think they would serve to improve the ctb version of the skin.
But anyway really well made skin.
