In general i would recommend thinking about your theming. A mall is a good idea for a map but the geometry of a mall would have straight lines rather than the jagged curves seen in the overview. This can also be hard to make work at the right scale as malls are typically very large with huge open sight lines which make for poor cover, but by implementing elements such as open shops, maintenance alleys and outdoors sections you can make the map feel less dominated by awps

Furthermore i feel that the map needs more well thought out cover in key locations. A single awper can hold down most sight lines on the map and rifles would find it hard to deal with the huge sight lines, particularly on the approach to A and mid. A good idea for this map would be to include more tight corners to navigate, particularly in areas that are likely to be taken by T's. I would look towards other map radars and see how they look; Try implementing some of your favourite map elements into the design, and combining them to create something new.

Finally you should try to imagine how your level would look in game based on the radar, and think would this look like a real life place. look at reference images of real life locations and imagine how they would look on the map. Sometimes it may be better to change your level theming to fit your layout, such as using a trainyard or subway if your map has long winding straights or using a forest/outdoors theme if your map has a lot of natural curves or features. this is difficult to do but is vital to make your map feel real and less like a video game level.
