From Mapping Advise Queue.
With this map, you achieved the goal you mentioned. The song is very short and the mapping is nothing unusual, so it was easier to get it ranked. Also, you hopefully had a lot of fun in the process. It's the perfect song and mapping style for a first ranked map.
However, simply getting your maps ranked will get less exciting when you have some ranked maps already. In order to keep your interest in mapping, you will have to experiment with songs from different genres and different mapping concepts than you're used to.
The problem with songs like this is that they are so short, that every section has the same intensity and rhythms. There is not much room for variety here. If you'll try to map longer songs (which you already did from what I can see in your Pendings) you will have to pay close attention, that the intensity of the map fits the intensity of the section in the song. This alone allows for different ideas within a map and will help you a lot to improve your mapping.
You already used a variety of generic mapping techniques in your map, that make for a very clean and structured experience, such as 00:02:594 (1,2) - copy-pasting and flipping sliders, 00:07:254 (1,2,3,4) - rotational patterns, 00:08:710 (2,3,4,5,6) - simple geometric shapes and 00:22:982 (8,9,10,1) - back-and-forth patterns. In the future, you should try to experiment a bit by using less common mapping techniques. You can get inspired by looking at other maps, or by using your own imagination when listening to a part of the song.
Before you start to map a song, you can try to think what makes this song special to you, or which parts stick out in the song. Then, try to think of special patterns or techniques that fit to this speciality of the song. In that way, you can make your map be more unique, and at the same time follow the song even better.
I think that's enough text for now, especially since you're not a native speaker. I hope everything was understandable, if not, you can ask me in PM! You can also ask me in PM for more feedback in case you'll try out to make a map with my advise. Good luck! :3
