This is my first icon-set, so any feedback is very welcome!!

Thanks!

it looks good! can you please change the elements to use Papirus colours - #e4e4e4 for white, #4f4f4f for dark grey (you can use a lighter grey, but please not in rgb format). also, the inner triangle could be better aligned to the pixel grid. for a bit of streamlining, it would be better if the elements are not grouped.

Thank you for looking at it! I'll take a look at the triangle, but it's a bit tough without changing the shape of the logo too much. Regarding the colours, the template itself was #fafafa for white:
