The new profile style is super clean and nice, I love what you did with it. WHERE DO YOU GET ALL THESE WACKY FONTS? Lol
But y'know, I think the main reason why people are having problems reading the text is that it's in a light color (white) and the font size is pretty small! The font itself (I don't remember what it's called exactly but I'm aware that it's the default userbar font, lol) is definitely not the problem. The giveaway profile does look good as is but changing the text color to black or something would make it stand out better, as the white text slightly blends in with the light gradient :-]
I like this latest icon! The cropping's great and the lighting/coloring is nice, with the monochrome purple color scheme going on. But I do have to ask, do you usually put borders on your icons (since most of the icon examples in the OP have a border)? I think borders are great on graphics like signatures but I would be cautious with using them in icons, since they can give an icon a bit of a closed look rather than an open one, especially since there's less canvas space. Also, there are overwhelming sharp lines in some parts, like her face and arm! You most likely left things that way to get some depth contrast with the right side but it's a good idea to tone down sharpen with icons, again because the canvas is smaller and it's more noticeable as a result.
(Here's my favorite smart sharpen setting, by the way: Amount- 30, Radius- 0.5px; and then after I sharpen, I use the eraser tool on a low opacity to get rid of anything that's too sharp.)
I use this setting a lot because the result often ends up sharpened just enough, though sometimes I change the amount up to 45 if the image is blurrier than normal and could use an extra boost. If you haven't already, you should experiment with some smart sharpen settings and see how you like it compared to regular Sharpen!
