It’s the letters SA (first and last letters of Systa)at a 90° angel, with the line in the center of the A removed and one of the little spaces in the S filled…
This is my first time designing an actual logo that doesnt just say the group name
Well, not trying to sound harsh but its a interesting logo, I didn’t see the S or the A it just looked more like a mouth. I would suggest making the logos words vertical instead of horizontal and also making them larger. I looked at your group and it looks too small compared to the gradient background. Overall its a really neat colour design and concept. Keep it up and you could do really well. - Just my opinion.
Edit:
I didn’t elaborate. Make the logo larger, vertical and I think it’ll look a lot better.
The simplicity of the logo is very nice (especially the mild gradients in the background), but as the others mentioned the correlation to the letters SA may be a slight bit too obscure (personally I saw a tidal wave over a beach). If you want to make them more recognizable I suggest turning them upright, but if you’re fine with the letters being hidden in the picture then don’t be pressured to change it.
As a quick side note, the back of the S peeks slightly through the A here.
That part was so annoying to fix, I had it zoomed in as much as I can to try and make it perfect, I probably spent more time on trying to fix the edges than the actual logo.
I ended up getting annoyed and just hoped no one would notice
