The big problem i see on that screen is sightlines, here the reason in more detail on why and what you can do against it:
The sightlines on viaduct are an exact reason why i dont like viaduct. On koth maps dont make it too easy for snipers. At least force them to take a bit more risks if possible. Koth maps already focus attack to be near the cp, and having a sniper safely behind it is a bad idea. On many other koth maps you have paths that barely interact with the cp in a sightline. Those paths dont interact with the sniper sightline and allow countering.
On viaduct you can at least decently counter the sniper sightline by taking the other side route which goes under his view. Although it requires you to battle next to the cp to counter - which again is bad. But lets say some examples that are better (as koth, or as midcp in a 5cp map):
king - you can use the lower path which although it has its seperate sightline isnt a primary used one due to lower traffic and easy countering from the top. All sniper sightlines have backroutes with easy access
granary - that higher path forces snipers to make use of vertical aiming aswel and it isnt visible on normal key paths for horizontal sniping since those dumpsters block it. Although its a small map and not as koth it shows why for koth it wouldnt be too bad
harvest - it has alot of strong sniper sightlines but also a 90 degree angle of attacking which brings the hazard to face other snipers too often. The sniper for that reason cant fully focus on each doorway that exists and this is a counter aswel. Thats simply the reason that the map is wide (your map is narrow for comparing)
lakeside - again a map i dislike but the inside area already is a blind spot for snipers. Its a higher traffic area though which is still why snipers arent easy to take out - but getting through it at least gives a reward of killing them.
But in your map i have the idea that the only way to counter the sniper is to jump into his face which isnt a counter (a bodyshot is still 150 damage). You realy need to do something about that sightline.
NEVER EVER help a sniper. A map that isnt sniper friendly doesnt have to be a boring map, a map that is sniper friendly can quickly become boring. Even 2fort which is considered sniper heaven has a path thats fully protected from sniper spam. Good snipers will allways find ways to exploit a certain sightline, and those sightlines are good since they have their restrictions.
Your cp looks good for normal gameplay and makes good use of heights, but that sniper sightline bothers me too much
