Some of the icons don’t look the same style of size. For example the world icon is on a bit of an angle (I’m not sure if this is on purpose) and it loos a bit smaller than the other icons because of the thickness of the lines compared to say the thickness of the lines on the chat icon in the bottom right.
Sorry but this is miles off
The preview image is very pixelated
certain icons are not in the middle of the BG e.g. YouTube
various inconsistencies in padding and alignment
