Fwiw, the proportions (at least looking at it in a photo rather than first hand) the proportions are different than your actual icons on the site... In relation to each other the center circle is bigger and the orbiting circles are smaller here, than they are on the sticker.

The placement of the name hubski may feel off to people because it is not in the power position. Ie: western writing systems that is the lower right hand corner...

I have not been here long, but it seems you might go with the paper choice of the gray background as it is on the site, if that is an option, and print the blue circles on that... As well as there is more bright white in the current sticker, comparatively, to what is seen on the site itself, unless on other devices hubski doesn't have the gray background.

And choose an ink closer to the blue of the badge, if not the exact color.

At first glance to the unfamiliar, the current sticker could resemble a Domino's pizza logo. No disrespect intended, but we're taught to watch how others' could read or misread any symbol or logo, and you always want to be distinct from any others that could be confused with your mark... And for old people like me, dial phones and Ma Bell blue come to mind, and there may be other associations as well..Not that young people would get that reference, but your ideal would be immediate recognition, vs taking several seconds or more to figure it out... So more reason to get it in the exact proportions, which are unique.

You might play with placement of the badge in the square and look at the composition of the elements together.

Here, there's very elegant placement and relationship to each other of icons and text, their varied weights and such, that is currently not showing on the stickers.

You might also consider doing an almost, but not fully filled badge...
