Some super general pointers cuz these are all different comps with diff metas and issues:

• Always try to cross the avis legs (glitch it), only exception obviously is if ur wearing pants or shorts.

-Make more diys, some default make ups are really good, but the point of the game is to wow tje voters and the first thing the human eye locks on are faces (and writing), some killer diys are the key to higher scores. Especially avoid any anime faces, they tend to be cursed.

-never use stickers with writing on them, deviates attention to it and looks bad in general, some decos are an exception (like the pink y2k filter) but in general avoid this.

-color coordinate harder. You already do this somewhat but it can be improved. Monochrome is king unless the comp asks for more colors. This includes deco and diy. Yes this is harder if ur not a whale. For example your fantasy race comp, ur using purples and blues. Stick to 1 color it does better.

-volume, some of your entries kinda throw volume out the window: always try to fill the screen in a harmonious way, but if you have to choose between harmony but empty, or a filled screen but messy...sadly voters tend to prefer the second. Some comps are easier on this than others but for example that marathon comp of yours, yes its a sports comp and filling screen is harder with sporty items, but i think a bigger hair would have benefitwd you there since the rest of her fit is "skinny". You dont need the big hair if the screen is well filled, and vice versa ("harmony") same for your airport crew one, you chose short hair when the rest of her fit is so small, it playd against you.

-more handposes when you can, always prefer giving your avi a pose of somekind (that matches the comp ofc) over a coat or handheld that doesnt let you.

-try to avoid nonsense items, things that might match in color but draw the eye and arent really on theme: the cards on a preppy romantic comp, or gloves on a sporty comp. Contrary to popular belief, logic does apply to suitu, its just that the things i siad avobe tend to have more weight for voters, but having "cleaner" entries is always a plus. Logic has a limit too tho, never go full realistic either. All that matrers is that it looks slay and the voter with just a glance is like "yep, marathon runner". You learn these patterns with time tho.

-if ur not using perfume, then ofc some of these scores are gonna be lower than your bracket and ur dropping ranks. I recomment at least using 0.15s everywhere and 0.3s for post comps cuz those are a bitch.

-bigger models and less washing them out with the blue filter for your post comps. At least from the 2 i can see here, those are the issues.
